Oil Siblings

Special bond between a guy and a girl created after both of them have had, alternatively or simultaneously, sexual intercourse with the same girl.

-Hey, Monica, guess who I tapped last night!

-Who?
-Jessica!
-No way, I did her last month. We're oil siblings!

New Sibling

when you meet someone, who you get along with great, and you find out that you have the same names. a very rare coincidence.
usually between a guy and a girl who share names, (like sam, page, eric, jordan etc...)

person 1: man i've really been enjoying talking to you, but you still haven't told me your name.
person 2: ohh its sam.
person1: MINE TOO!!
person 2: you are totally my New Sibling!!!

sibling switcher

when someone dates one sibling, they break up, then the person dates their brother, then on and on with the family like how a homie hopper jumps homies, but it's siblings

"Dude he's such a sibling switcher, he dated me now he's with my brother"
