Rousey's icy gesture brought upon her a smattering of boos from the sold-out MGM Grand Garden Arena in Las Vegas, Nev., and the booing continued throughout her post-fight interview with UFC color commentator Joe Rogan.
Rousey, who defeated Tate via armbar at the 58-second mark of the third frame, told Rogan that she has no problem playing the role of the bad guy.
Rousey explained that the boos don't bother her, and her walkout song, Joan Jett's "Bad Reputation," was proof enough that she isn't just blowing smoke.
Rousey doesn't care if she's seen as a villian or a face by fight fans. She just wants to be true to who she is, and there's really nothing wrong with that.
Tate, 27, got up and offered Rousey a handshake after losing to her in the UFC 168 co-main.
Rousey, 26, looked at her and walked away in icy cold fashion.
Rousey's whole gimmick and appeal is that she is "mean," but that's she's "real mean." If she doesn't like you, she'll tell you to your face and not try to act "fake nice."
That would explain why Rousey didn't shake Tate's hand. Rousey admits she never liked Tate, so there's no reason for her to shake her hand.
She often complains that Tate talks trash behind her back and then acts nice to her face in an attempt to play the role of the victim.
At the UFC 168 post-fight presser, Rousey said she would only shake Tate's hand if she were to offer an apology to her entire coaching staff.
Tate refused that offer, so the "beef" lingers on.
Rousey's next fight has already been announced for Feb. 22 in Las Vegas, Nev. She's set to fight Sara McMann.
As for Tate, no word yet on what's next for her.
