Ronda Rousey mocks Floyd Mayweather

UFC superstar Ronda Rousey has once again mocked boxing champ Floyd Mayweather, opening up over her “how does it feel to be beaten by a woman” sledge and how she earns more money “per second” than him.

Speaking to US talk show host Jimmy Fallon, Rousey was asked about her infamous pot shot at convicted woman beater, Mayweather, after she won the 2015 ESPY award for "best fighter".

"I said something to the effect that now he knows what it feels like to have a woman beat him for once," Rousey said.

The UFC queen and Mayweather have been feuding for months, with Rousey claiming she could beat him in a no-rules mixed martial arts fight, which the boxer dismissed.

The irony is that Mayweather continues to claim that he does not know who Rousey is, although she promised to continually introduce herself when they cross paths.

Asked whether she had received any texts from Mayweather, Rousey said: "He still maintains he has no clue who I am so every time I run into him I'm gonna reintroduce myself to him.

"And maybe one day he will actually remember me," she smiled as the audience burst into laughter

Rousey, who has dabbled in acting, also fired a verbal jab at Mayweather's earning capacity in the wake of the welterweight champion's boast that he is making about $300m (A$416m) annually.

In response, The Fast and Furious 7 star said she earns more than Mayweather "per second" because she is more efficient at winning her fights.

Of course the real fight that many would love to see would be Rousey taking down the controversial boxer.

But she has repeatedly dismissed such a notion, adamant that a woman should never be put in a position where she can be hit by a man.

And who can argue with that.
