A word based on the acronym D.A.F., meaning Down as Fuck. A term commonly used to accept invitation to a social event or gathering, such as a party, mobbing, shindig, etc. Basically the same as saying "I'm down", though much cooler and eccentric.
Karl: Yo Gary, you down to go to that mobbing party at the Shindigersons tonight?

Gary: Heck ya, man. I'm daffing.

Karl: Cool, dude. I'm glad you accepted my invitation to this social gathering at the Shindigersons.
