JAF
An acronym for Juciy As Fuck, used to accurately described a person who has consumed a large amount of GHB (juice) and is expressing themselves is a dramatic way to the amusement or possibly horror of those around them.
After consuming a fair amount of GHB (juice), Bob was so JaF, that he pulled out his cock in front of the police thinking they were festival transgendar harlots. Instead of getting his cock smoked he got arrested. Bob was JaF.

JAF
"Just a friend"; a term often used to describe someone of romantic interest who has yet to be referred to as "boyfriend" or "girlfriend" in public or even among close friends. Often, both parties have a shared romantic interest in each other and haven't told anyone yet. At other times, one of them may be stuck in the friend zone. The "just a..." part is a lame attempt to conceal this fact everyone else already knows. Otherwise, the term friend is used instead.
Jay-Z was jaf to Beyonce for years and now they are married!

I respect people's privacy but who were they fooling?
