FAF is an online acronym for the phrase "Funny As Fuck". Some believe that it originated from the popular t.v. character Lisa Simpson who quite often said, "FAF" while laughing. Others just believe it originated from stupid teenagers who didn't want to conform by using 'lol' or 'lmao'.
1)Bob:insert funny thing here
Bill: FAF! True be 'dat!
2)Dude, that is FAF

(Example two is not used as often for it doesn't make that much sense and anyone who does is just a complete moron. CONFORM, SMOKE, EAT.)
