aww man that is absolutely lowball stuff.

u sound like the only person here that genuinely cares about what happens to this girl and somethign like that happening to her could really and i mean REALLY **** her up big style.

i suggest wot u do is tell her what they're doing but dont let her know how vicious they're being just tell her their winding her up trying to get her to meet and have a lauch with her and tell the girl to tell the person that either shes not gay and was just a bit confused or something or just say she was having a laugh pretending (of course she wont tell ur mates that r doing it that she knows its them)

or u could tell her the full script and just suggest she totally ignores the people when theyre online so they cant get anything else on her.

thats not totally covering her back but it seems the best idea to me.

and why the **** was ur best friend going about showing and tellign people anyways as if they wouldnt go about spreading it?
