LOL that has to be the most hilarious thing i have heard in a long time! That would be straight up lame of him to tell your brother. Theres really no reason for it and lke you said that will prolly just make him mad at the dude and not u :P well except the fact that u had sex in your brothers bed :P

It's hard to "win" an arguement with an ignorant person.. I have the same affections for my brothers friends... yummy!!!! I'm still his sister.. and they are no longer his friends... gotta hate that blood thicker than water shit.. and tell brother dearest.. sheets can be washed... I said "can be" not that I did?! ha!

OMFG that is hilarious!!!!!!!!! i cant believe he would try and blackmaili you that way lol. what did he expect to gain from this?

what he wins= no more fubu (ever), no more best friend(go ahead piss off a marine about his LITTLE sister see how that goes) and a nice big ass whooping.

what you win= got rid of an idiot, finally come out with the truth(which your bro would want) and still cool with you bro

conclusion= he losses hardcore either way GO FOR IT DUMBASS
