I feel your pain.Well, it's not talking shit. She just says things like "You must be a complete buffoon if you think I am going to sit here and listen to you be an asshole," or "I bet you don't have the balls to say that to my (or the other person's) face" ...or "you're a complete loser because I am sure no girl will ever want to fuck you because you're so full of yourself" ...something along those lines. ...This is all in response to this one kid who made fun of her former roommate (...she hates both her former roommate and this dude who is a jerk to her roommate). ...For funsies, she'll make fun of the person for something completely random, like if she hears the person play piano she'll say something like "....oh, you think you can play that song well, but you really can't. Why can't you face the fact that you're a shitty person AND you can't play piano well." Or if the person's voice to really loud, she'll use that against him and say something like "You feel very insecure so that's why you think you have to yell... BEAUSE NO ONE WANTS TO LISTEN TO YOU!!!"
