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.

demon twins

two siblings that take 0 fucks, and could care less what you think of them, usually found in the shadows, watching your every move, Onyx (cm), the older twin will make it clear what they think of you, Orion the younger, smarter twin is more mystery, you never know where you stand with him unless he tells you flat out. These two you don't f with unless your want your mentality screwed up. They lead a close knit team of people, their names are unknown still.

"aye, you seen the demon twins lately?"
"nah, they chose to keep close to their team, good luck infultraiting them, they don't let the average scum join their ranks."
