fse 

'fse' is a phrase used when you just witnessed a funny moment, or watched a funny video.

It means: funniest shit ever.

It is often used by teens online.

It is a phrase too awkward to say in real life though.

person 1 - "HAHHAHHAHAHA I"m crying because that was so funny! I'm dying of laughter"

person 2 - "dude, seriously? just say fse. Because that was the fse."
