Fun things like that never happen to us guys. My wife and several ex girlfriends all talk about being harrassed in the silliest ways by random punks; even my mom when walking with my grandmother has been targetted by crazy people literally in the middle of a busy supermarket on a sunny Saturday. But I've never once been or been there when it happens. Women truly have a different experience than men, always talking about not going out at night, avoiding certain streets, walking to the other side of the street if anyone looks funny, etc... while guys just go anywhere anytime we want.
This is exactly one of those times. The dude didn't dream that chick knew Muay Thai. If he bumped my mom and got racial with me, I would have made sure to leave him with the ugliest most noticeable permanent disability and I would have gotten extremely racial cursing him out as I beat him within an inch of his life, far longer than he'd stopped defending himself. I truly wish I get an oppertunity like that in China because I'm just dying to let loose everything I've trained for. But it would never happen to a guy... or a girl walking with a guy. If a fat loser like him sees a guy, he'd be the nicest fella you've ever met.
