Faf. 

An acronym of "Fake as fuck", a term popularised by rapper Del Tha Funkee Homosapien in his 'Both sides of the brain' album (2000), denoting his view of two-faced people who say one thing to your face, and another behind your back.

"If you're brown nosin' in the industy (you fake as fuck)
Wanna pretend that you're a friend to me (you fake as fuck)
Funny style record companies (you fake as fuck)
Weak ass MC wannabe's (you fake as fuck)"

You know that dude Jackson? How he's always smiling and slapping your back, telling you how rad he thinks you are? Yeah, that's faf. He hates your ass.

Fratty as Fuck. A phrase describing a bro on all standards. The guy at a party that runs shit. He has the biggest entourage, can outdrink everyone, is wasted as shit, and still gets the finest pieces in the joint, often times two at a time. In summary someone who wherever they role, don't give a fuck because shit either goes their way or they make it so.

Yo how is he leaving with them three sorostitue dime pieces when he was just telling them to fuck themselves?
