JFF 

Acronym for "Just Facebook Friends", similar to and playing off the term BFF but with a generally negative connotation. This applies to those people whom you rarely see in real life, but know everything about thanks to their frequent social network updates. Alternately used to downplay a relationship with a person you do not wish to be associated with publicly.

Alt. Form "J.F.F.F.L", pronounced "Jiffle", meaning "Just Facebook Friends For Life".
