WBIS 

A short term that means Welcome Back from Iraq Sex. Take out the from. When a married man or a man with a girl returns from Iraq, the couple usually has Welcome Back Sex for about two to three days. All this sex usually ends with a baby.

Sherry: Tina I haven't seen you around for about 3 days since Jim came home from Iraq.

Tina: We've been having WBIS for 5 days stright and we're having a baby!!!!!!!!!

WBIS 

White Boy(s) I(’d) Shag.
Although this terminology may seem a bit discriminative, it is not! It simply expresses the fact that, even though some women aren’t attracted to white males (yes some aren’t, can you believe it?) there are still some of them they’d shag.

Chick #1 : What do you think about that guy from Manchester By the Sea?

Chick #2: Who? Casey Affleck? I heard he’s a knob end but I don’t know, he’s been part of my list of wbis
