Jimmy Kimmel and Sean Hannity have been trading tweets back-and-forth all day, but this is the one that should leave a mark.

Here’s the late night comedian using being gay as a punchline, implying that’s he’s a “bottom” with President Donald Trump as the “top”:

Don't worry – just keep tweeting – you'll get back on top! (or does Trump prefer you on bottom?) Either way, keep your chin up big fella..XO https://t.co/R4QJCoGYCL — Jimmy Kimmel (@jimmykimmel) April 6, 2018

Kimmel is getting called out over it from both sides, but let’s see if anything really comes of it:

I swear to Beyonce if you straight people don’t STOP making things gay because you can’t find a way to be clever or original in any other way, we will impose sanctions and cease aide! https://t.co/8L9DX3hEE6 — Phillip Henry (@MajorPhilebrity) April 6, 2018

"Bottom" isn't a punchline. "Gay" isn't a punchline. That aside, how are you this bad at jokes? https://t.co/aWCw4noWBe — Louis Peitzman (@LouisPeitzman) April 6, 2018

.@jimmykimmel Is that a homophobic slur? After discussing Hannity's underage daughter And making fun of #FLOTUS accent? You are everything the Left claims to hate#LiberalPrivilege https://t.co/QZ9ZwSsXPJ — Jim Hanson (@Uncle_Jimbo) April 6, 2018

Congrats, Jimmy, on joining up with Chelsea for "Being gay is such a funny punchline" Friday. https://t.co/7AhDFP6OUa — Chris Geidner (@chrisgeidner) April 6, 2018

Every time a liberal wants to insult a Republican, they imply they are gay. Never fails. https://t.co/BR5r2Gi8tO — Chad Felix Greene (@chadfelixg) April 6, 2018

Going to risk ruining my mentions and saying this in all-caps for the cheap seats: MAKING THIS KIND OF JOKE ABOUT A MAN HAVING ANAL SEX WITH ANOTHER MAN IS HOMOPHOBIC, AND NOT FUNNY. THE "LAUGH" COMES FROM THE IDEA THAT GAY SEX IS INHERENTLY SHAMEFUL, AND I'M NOT LAUGHING. https://t.co/LIkA5tktum — Adam B. Vary (@adambvary) April 6, 2018

Straight people are exhausting today. https://t.co/77mdLZOlCp — Gabe Gonzalez (@gaybonez) April 6, 2018

Sean Hannity did fire back with the same accusation, however:

Harvey Jr, @realDonaldTrump and I don’t have the creepy perverted relationship that you must have had with Obama. So Stop projecting. For the sake of 18 year old girls in America, Have you thought about going to Harvey Sr’s Sex Rehab? #pervertkimmel @Disney https://t.co/PlOeju5cAl — Sean Hannity (@seanhannity) April 6, 2018

Sigh.
