I would just flat out say "hey, you put yourself in this position. Don't blame me."

Me and my roomates were playing strip beer pong which involved only one girl and five guys well we were making up impossible rules for her to agree to take her clothes off we were fooling around and we were drunk I had no intention of pickng this girl up I didnt hit on her and basically showed no intrest in her. She threw a bal at my face and I called her a bitch she told me five times to suck a dick i said thats why we brought you but hey an hb8 strippin was all i really noticed anyways we got her down to underwear and bra. Everybody was failing then i made a 35 foot swish in to the cup for the bra. I was highfiving with my friends because it a big deal then she said she didnt want to it didnt count everyone was telling her to take it off everyone looked at me and i said a deals a deal sealing her fate so it came off later i was just fooling around shooting around when one went close to her i said sorry off hand at went to go pick up the ballthen she said this
hb:U nnkow what I dont like you your not my friend
me:(pisssed off) when the hell did I ever say I was your friend, I dont even know your name. I dont like you either and I dont care

it ended in mutual hatred i admit im a little bit of an asshole when im drunk but not a huge one she was probably pissed at everyne for basically peer pressuring the crap out of her but she took it out on the person she just met i need to know about how to respond a bitch comment and a frustrated hb having a bitchy attitude

Well to be fair, it sounds like you were a total asshole to her, so it's not surprising that she counters with the bitchy attitude. But when she said the "you're not my friend" line, how did she say it? Because you were being the typical bad boy and she may have been attracted! Unfortunately, because you were so drunk, you went overboard and made her bitch shield go up 300%.
