FSB

Fuck-Shit-Bitch = FSB

Inspired by the clasic tune known as Mo bamba by Sheck Wes

It's used as a curse word replacing the usual "fuck", "shit" or "bitch"

Instead of saying one of those you say fuck shit bitch and then continue rapping the song.

If you were to use it in a text convo just write fsb.

It also keeps up the good mood after an inconvenience happens.

*stubs toe* "Ah fuck, shit, bitch ... YOUNG SHECK WES AND IM GETTING REALLY RICH"
Dude that girl makes me wanna say fsb..

FSB

short for Flight suit boners, and occur when you are a pilot and you see some fine ass female while wearing your flight suit and you start to grow a full on rager, but instead of hiding it, you MUST flaunt it.

Hey Dan, is that an FSB i see?
You know it.
