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.
