I think “Average Fucking Chump” is funnier, but it’s a cool term I picked up reading the new Neil Strauss (he did the Motley Crue and Marylin Manson) book The Game.
AFC = Average Frustrated Chump: A “nice guy”. A guy who has no pick up skills and rarely manages to get pussy. Also a guy who tends to supplicate in his behavior to HBs (Fuck Buddies). Meaning, buying flowers for a chick when going out for coffee, putting her on a pedestal, and generally letting women walk all over him in the vein hope of somehow being seen as attractive in their eyes. A common term used for AFCs that have seen the error of their ways but not yet gained PUA (Pick Up Artist) skills is RACF (Recovering AFC).
