Ronda Rousey had to be taken to the hospital after Holly Holm's kick knocked her out. This didn't stop the Internet from being relentless. You probably seen the memes by now: The Michael Jordan crying face, the Lion King, the Rocky Balboa/Tony "Duke" Evers. At this point, it's about who's posting the memes.
Mayweather can't be bothered to post a meme, and he's instead promoting The Money Team to complement NSFW videos of women twerking.
