This is the only
definition of ff that matters for the purposes to this
dictionary:
adj.
1. freshly fucked, as in a way of describing a big, ratty, messed-up hair-do that looks as if its wearer just got plowed something fierce in the back seat of a Chrysler LeBaron. Especially
popular in the 80s and early 90s, the ff look is making a bit of a comeback today. Technically, one can be a virgin and still sport the ff look.
2. short for 'the ff look', or 'the freshly-fucked look'.
