What the girlfriend of your buddy does to you when she has no friends and you hang out with her, but she then goes home and tells your buddy that you did nothing but talk about his ex girlfriend. Which you didnt. But he takes her side because she gives it up to him. causes your buddy to freak out and start hurting people.
She totally sand bagged us after dinner. She went right home and complained to her boyfriend that we were talking about his ex or some shit. She's a total sand bagger!
