Conor McGregor may have met his match when it comes to Twitter zingers.

The brash UFC featherweight contender was among the many fight fans who watched Saturday’s UFC 180 event, where Ricardo Lamas (15-3 MMA, 5-1 UFC) picked up a pivotal victory over surging 145-pounder Dennis Bermudez (14-4 MMA, 7-2 UFC) on the pay-per-view main card.

As the fight wrapped up and Lamas celebrated his submission victory, McGregor spotted Bermudez wearing one of his signature hats (via Twitter):

Hard luck Dennis Bermudez. You wore my 'Stay Ready' line with pride. We are all proud of you here at McGregor Inc. pic.twitter.com/qxmKi87SzW — Conor McGregor (@TheNotoriousMMA) November 16, 2014

The “McGregor Inc. CEO” then turned his attention to Lamas, who had called out McGregor after UFC 180 and said he wanted to give the Irishman one final test before any potential title fight. McGregor, meanwhile, criticized Lamas for his five-round title loss to champion Jose Aldo earlier this year (via Twitter):

I would've sponsored Lamas too, only he fought like a pussy against Jose. McGregor Incorporate does not reward pussies who run for 5 rounds. — Conor McGregor (@TheNotoriousMMA) November 16, 2014

But Lamas? He suggested a better use for any McGregor-branded gear (via Twitter):

So disappointed I can't be sponsored by your clothing line…… It's the most absorbent toilet paper I've ever used. 😭 — Ricardo Lamas (@RicardoLamasMMA) November 16, 2014

While the framework is now in place for a potential future grudge match, McGregor has other challenges ahead of him. Before he’d possibly fight Lamas, who’s ranked No. 5 in the USA TODAY Sports/MMAjunkie MMA featherweight rankings, No. 8 McGregor (16-2 MMA, 4-0 UFC) needs to get by unranked Dennis Siver (22-9 MMA, 11-6 UFC), whom he meets Jan. 18 at UFC Fight Night 59 in Boston.

So, for now, McGregor’s simply focused on the business (fighting and otherwise) at hand (via Twitter):
