S.W 

Basically a person that you just refer as a dumb bitch, S.W Means Stupid Whore, you can uses S.W to insult someone who wouldn't even know what your talking about, use this on your enemies, or you could jokingly use this on friends but before you insult them to their faces, please tell them that you are only joking so that way the do not stop being your friends because that would probably suck.

FAKE NAMES!!

John: Jeff you are such an S.W /j

Jeff: What does that mean?

John: I called you a stupid whore, but you know im just joking bc you are my bestie :)

Jeff: :)
