FOF 

Frown on Face: the negative analogue to LOL (laugh out loud). Thought up on episode 230 of the Engadget Podcast by Joshua Topolsky, Nilay Patel and Paul Miller.

Throwing chairs at Jon Rubinstein's PR people makes me FOF.

Friend of a friend. Like an acquaintance but with a little more familiarity, because odds are you've heard of them and they've heard of you and/or you've seen each other around the same crowds. Not quite a bff or a homeslice yet, because you haven't interacted with them enough to get those bonds yet.

Text1: So who's throwing the party?
Text2: A fof, she seems legit at the parties I've seen her at.
