My sister knows a chick who went to Miami with him and she said he's a sleeze.
I met a chick once who made a similar claim. She went to the same college and said the same thing your sister's friend said. But who knows if she was just talking to be talking. I don't understand this "sexual assault" thing. If a chick doesn't want to bang you then why would you go to that length? If a chick even as much as hesitates I no longer want to bang her, even if she changed her mind I wouldn't bang her.
