How do you top a 16-second knockout? Apparently you submit your toughest test two seconds quicker.

There simply aren't enough superlatives to describe what Ronda Rousey is accomplishing right now in women's MMA. Rousey remains the undefeated UFC women's bantamweight champion, finishing Cat Zingano on Saturday night at UFC 184 with an inverted armlock that Rousey later admitted to never actually drilling in a live practice. The entire scene was equal parts precise, smooth, surreal, and stunning. And, for once, even the pros were left speechless.

In hindsight, that may not have been the best game plan. #UFC184 — Joe Lauzon (@JoeLauzon) March 1, 2015

wowwwwwww congratulation @RondaRousey — Antonio Pezao Silva (@BigfootSilva) March 1, 2015

Even though I knew what was going to happen... My mind is still blown @RondaRousey #UFC184 #1stRoundArmbar — Zachary Makovsky (@ZachFunSize) March 1, 2015

I have a feeling a lot of 135ers are gonna be dropping down to 115 for my belt with a performance like that! #unstoppable — Carla Esparza (@CarlaEsparza1) March 1, 2015

Sooooooo..... What would make you believe coming out the corner with a flying knee in your title fight is a great idea? — Will Brooks (@illwillbrooks86) March 1, 2015

Award for highest ratio of fucks in any interview ever goes to Cat. Sucks after a loss... But that's exactly what's we're thinking. — Joe Lauzon (@JoeLauzon) March 1, 2015

Hilarious submission Ronda is a beast #UFC184 — C H I T O V E R A (@chitoveraUFC) March 1, 2015

She's just light years beyond in athleticism and skills — David Rickels (@TheCaveman316) March 1, 2015

Ronda just unbelievable!!!!!!! — Douglas Lima (@PhenomLima) March 1, 2015

Mad Respect for Ronda #UFC184 — Jon SuperSaiyan Tuck (@JonCruzTuck) March 1, 2015

@CatZingano you made the same mistake I made with you, I know this feeling when you feel so confident. GOD bless you. — Amanda Nunes (@Amanda_Leoa) March 1, 2015

Man...lost of words from Cat Zingano. That really blows....Like major ball bags. #UFC184 Sheeesh what a finish! — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

Fighter I.Q is so underrated — Will Brooks (@illwillbrooks86) March 1, 2015

Usually title fights are a 5 round war. That's 2 you can actually fit the entire fight in an Instagram video #UFC184 @RondaRousey — Chris Clements (@menaceclements) March 1, 2015

Holy shit what was that? I just kissed my son and it was over — Ruslan Magomedov (@MagomedovUFC) March 1, 2015

Cat keeps swearing, I swear this was children's television — russell doane (@RussellDoane135) March 1, 2015

That was fast, sweet armbar by @RondaRousey . It's easy to talk from the stands. Congrats to @CatZingano for making history again. — Leslie Smith (@LeslieSmith_GF) March 1, 2015

That Judo transition was too slick! #UFC184 — Jon SuperSaiyan Tuck (@JonCruzTuck) March 1, 2015

Damn! Great win for Rhonda but it sucks that Cat got caught so early and we didn't get to see a great fight :( — James Vick (@JamesVickMMA) March 1, 2015

. Didn't get into the fight at all. Wild, random, and heartbreaking — Brian Ebersole (@TwasEbersole) March 1, 2015

@RondaRousey is insanely good. Wow. That was impressive even for some who is always impressive #UFC184 — Chris Clements (@menaceclements) March 1, 2015

Best female fighter of the world no doubt ! — Sergio Pettis (@sergiopettis) March 1, 2015

Yep...this division victim of the Rousey era. There Evil out there...somewhere that might have something to say about that. #UFC184 #EvilEye — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

That's why you don't sprint towards a lion. — Coach (@CMPunk) March 1, 2015

WELCOME TO THE UFC

Wow, Holly Holm with the most nervous energy I have seen in an entrance, looks like Octagon jitters affects world champs too. #UFC184 — John Hathaway (@ufcjohnhathaway) March 1, 2015

Not too sure about Hollys ground game though — Randa Markos (@randamma) March 1, 2015

Holm looks a lot bigger than Pennington — Brad Tavares (@BradTavares) March 1, 2015

Holly is looking for that head kick for sure — Alptekin Ozkilic (@alpozkilicmma) March 1, 2015

Damn Holm is fucking huge at 135 though — Kevin Lee (@MoTownPhenom) March 1, 2015

Wow these girls are hitting a bunch of air! Most missed punches in a UFC fight, I usually love watching the ladies fight.. — Tim Elliott (@TElliott125) March 1, 2015

Holms verbalizes every strike like a tennis player hitting a serve #huhhuhuh #UFC184 — Angela Hill (@AngieOverkill) March 1, 2015

Holmes just made me pee a little with that head kick....#scary — Brandon Thatch (@RUKUSMMA303) March 1, 2015

Pennington's corner better pray to God that Holm head kick keeps missing — Will Brooks (@illwillbrooks86) March 1, 2015

Most side-kicking shit I've seen in any fight...ever. Don't know if I'm in like or awe that Rocky hasn't caught one yet. #UFC184 — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

This Co-main fight is garbage — Big Ben Rothwell (@RothwellFighter) March 1, 2015

Holm is winning the point sparring match...but doing 0 damage vs a grappler who can't take her down or get inside to strike effectively — Brian Rogers (@BRogthePredator) March 1, 2015

For those saying holm was the one to out strike and beat rousey. Pennington has got in to clinch multiple times but isn't strong enough to — Brian Rogers (@BRogthePredator) March 1, 2015

That was an amazing fight! @RockyPMMA and @hollymadison had this whole stadium on edge! — Leslie Smith (@LeslieSmith_GF) March 1, 2015

@RockyPMMA has grown a lot! Not sure who won but that was a great striker she stood with! @ufc #ufc184 — Tyron T-Wood Woodley (@TWooodley) March 1, 2015

Close but I reckon Holm got it. I'm not all that excited to see her fight Rousey yet — Angela Hill (@AngieOverkill) March 1, 2015

Great win @_HOLLYHOLM that was not a split!! Great performance — sheldon westcott (@sheldonwestcott) March 1, 2015

Idk how anyone can even determine how judging works. This is embarrassing and disrespectful to the sport. #ufc #holm — Tony Martin (@tmartinmma) March 1, 2015

I never want to see anyone get booed but I agreed with the crowd. I thought @RockyPMMA did more damage. — Leslie Smith (@LeslieSmith_GF) March 1, 2015

Sorry I didn't think that fight was close I thought Holly won every rd. Definitely wasn't a split decision — James Vick (@JamesVickMMA) March 1, 2015

THE JUGGERNAUT GETS BACK ON TRACK

Kos hasn't been the same, IMO, ever since his eye got busted by GSP. I still like him and I'm pulling for him right now. #UFC184 — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

Is it me or is Ellenberger a little overrated — Will Brooks (@illwillbrooks86) March 1, 2015

MOAR FOOTSTOMPS. I spam those in UFC EA because I don't know the buttons — Angela Hill (@AngieOverkill) March 1, 2015

Ellenberger seems different since his fight with Kampmann. Doesn't let em fly like he use to. #UFC184 — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

Wow nice choke @EllenbergerMMA — Brad Tavares (@BradTavares) March 1, 2015

That was a beautiful sub — Randa Markos (@randamma) March 1, 2015

Kos's eye has never been the same since that GSP fight — Will Brooks (@illwillbrooks86) March 1, 2015

That replay though — Randa Markos (@randamma) March 1, 2015

And another bites the dust. #UFC184 — Jerome-Max Holloway (@BlessedMMA) March 1, 2015

Something tells me the foaming at the mouth thing is going to be memed to death #UFC184 — Angela Hill (@AngieOverkill) March 1, 2015

KOS didn't seem like he wanted a fight, and Jake looked like he lost some of his vintage killer instinct. Jake back in Win column. #UFC184 — Aljamain Sterling (@FunkMaster_UFC) March 1, 2015

NEVER MESS WITH A MODEL

Props to Big John on that stoppage. #UFC184 — Scott Holtzman (@HotSauceHoltzy) March 1, 2015

That clinch elbow game is underrated in MMA. Nice KO by Jouban. #UFC184 — Scott Holtzman (@HotSauceHoltzy) March 1, 2015

Another awesome finish — Randa Markos (@randamma) March 1, 2015

You win some you loose some . Thanks to all the people who support and believe in me . Love you all — Richy Walsh MMA (@RichyMMA) March 1, 2015

EL CUCUY HAS ARRIVED

Very impressive performance by Ferguson! #UFC184 — Cathal Pendred (@PendredMMA) March 1, 2015
