What to do friend has a prick of a bf?

My best friend has the new boyfriend usually she gets a new one every other week or so XD but she says he's special and different she's already met his family ect.. (we are 15) but hes a complete prick. She called me and said she was spending the night at his house, and every time she spends the night at a new bf's house I give em a little threat. But she said not to because he was different so I just kidded around with him. (I haven't met him face to face yet) and now she tells me he wouldn't like me at all and won't introduce me to him, because he already dosen't like me because of what I said on the phone. (alls I said was yu aint getting into her pant mister she's mine) and he hates me. She keeps telling me he wouldn't like me and she's embarred to introduce me to im because I kid around. (this has never been a problem before) what should I do? Our friendship is getting really stressed and she has only been with this guy a week?
