so the other night i was at a party and saw a friend of a friend i had never actually met but saw pictures of over myspace. anyways i didnt really have any intention of picking her up, just wanted to introduce myself to her and make friends. anyhow while we were talking her creepy boyfriend rushes in out of nowhere and shakes my hand to make the point that he belongs to her. anyways i froze up because i truthfully didnt expect to be caught in that situation, so i politely got myself away. now for future reference, what's the best way to handle a shitface like that guy?

Not sure but I would probably say something like:

"I love how your boyfriend keeps you away from other guys *wink*. I'll talk to you later!" then walk away
