Let see off hand I can think of two chicas others knew as well as me.
One chica I wrote about before is Krisha who worked at Hong Kong she was killed in a car accident. But it's pretty well known that she got her ass kicked by three chiicas, because of of those chicas saw her sitting with a guy who she considered her boyfriend. And I mean they kicked her ass good, leaving her with two black eyes and a puffed up face. ( Donavan, and Melonbag from TJA could verify the story for you)
The bad chica I knew worked at Rita Rosas named Alma, she worked there on and off for 4 years. She use to work at Hong Kong, but got fired for fighting. She was fighting over a guy, she claims the other girl started it, but she was all proud of herself for kicking the other chicas ass, and if I recall she said she threatened her with a knife too? Alma was a little tiny chica, but she was tough, and nasty too. Later after I did her in a hotel room, I find out she did someone I knew sin-condom in the bar! Alma for me was very nasty in the bar, but when I took her to the room, she turned boring. I found out later the secret to this bar is fucking the girls right there in the bar in a dark corner for better nasty action and sometimes you can do it on the price of drinks alone, but you have to buy lot and lot of drinks. ( check with Eric on TJA or others who go to this bars, as Alma was well known, she isn't there now, but I'm sure will return)
