siamese twinning 

When you are being cock-blocked so hard by a girls friend that she doesn't leave her side the whole entire night.

Guy: Yo, did you get with Emily last night?
Me: No man, she was siamese-twinning with Lily the whole time.

That girl is always siamese twinning with her friend, you never have the chance to make a move.

Siamese Twins Game 

A game which is played by two males or females in which the participants where a XXXXL sweater and cover themselves with a comforter whilst pretending to be Siamese Twins and engage in the act of mutual masturbation. This raises the question: 'When Siamese Twins rub one out is it an act of masturbation or incest?'. Either way is is a rather disgusting act meant for homosexuals.

Fred: Hey Tom wanna go to the Mall?
Tom: No, I plan on playing Siamese Twins Game with my Cousin, Billy-Joe.
Fred: You're a disgusting fuck-bag, you know that?
