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.
