SFF 

An acronym for "So Fuckin Funny". To replace the much lamer LOL for "Laugh Out Loud". Implies utmost hilarity. Generally used in text or instant messaging; can be used as an adjective or on it's own.

That comedian last night was SFF!

His yo momma joke was classic. I couldn't stop laughing. SFF!
