Ronnie MOCKS Situation -- How Ya Like Them Abs?

As if kickin' Situation's ass wasn't bad enough, Ronnie then mocked him by stealing his trademark d-bag move of lifting his shirt and flashing his abs to fans on the street in Italy yesterday.



As TMZ reported yesterday, Ronnie beat up The Situation the other day -- leaving Sitch with red marks all over his face and left eye.

GTL now stands for gym, tan, laugh at Sitch.
