It looks like Floyd Mayweather Jr. is getting the last laugh in his back-and-forth feud with Ronda Rousey.

A day after the UFC star was upset and brutally knocked out by Holly Holm, 50 Cent took to his Instagram account Sunday to post one of the many memes on social media poking fun at Rousey and he said his friend Mayweather asked him to post it.

The meme depicts a scene from Rocky IV, in which Rocky (Sylvester Stallone) tends to Apollo Creed (Carl Weathers), who was killed by his opponent during a bout match — except an unconscious, bloody Rousey is the one in Creed's place.

Rousey has taken plenty of shots at Mayweather, so this was a way for the retired boxing champion to get her back. 'Fif went on to post two more memes at his own volition, too, with the last one depicting a fallen Manny Pacquiao on top of an unconscious Rousey in a precarious position with the words, "Netflix and chill."

They weren't the only ones to kick Rousey while she's down. Former boxing champion Laila Ali told TMZ Sports, "In order to be the best in the world, you definitely don't ever get beat up like that in your prime, period," about Rousey's loss to Holm. Ali added that if Rousey was to face Holm again — as expected — she'd get an even worse beating the second time around.

Despite being a heavy favorite, Rousey was no match for Holm, a boxer turned MMA star. After feeling the brunt of a vicious knockout, Rousey was admitted to the hospital.
