look up any word, like pussy:
An extended period of time in which one or more individuals DGAF. Participants of a DGAFathon couldn't care less about the subject on hand, be it school or life. A DGAFathon occurs naturally when an excess of bullshit manifests itself without the danger of consequences haunting the victims.
Dude 1: Hey, are you doing the physics worksheet?

Dude 2: Pfffft, physics? That class is a DGAFathon. Just turn in last week's worksheet.

Dude 1: I didn't do that one either.

Dude 2: Dude....fuck it.
