BSW 

BSW is the, rather, an acronym for "Bitch Says What". Both a question mark and/or and exclamation point can be added to the end of this word(s).

Man 1: Dude, I had sex with your sister last night.
Man 2: BSW!?
Man 3: OH SHI-
Man 1: It's not my fault, she came onto me!

Dude: I think it's time you get tested.
Dudette: BSW?!

A: Sorry, I can't be there, my husband and I are going up to Big Sur for a few days.

B: Sounds nice. BSW?

A: I sure hope so.
