An acronym for the words 'Down For A Sesh/Session'
The sesh/session here refers to a period where 1 or more people are smoking marijuana.
Johnny: Oh my God, I've had such a bad day.
Caroline: Really? DFAS to cheer you up?

Savannah: LETS GET DRUNK AND PARTY!
Paige: Na, I don't want a hangover , I'm working tomorrow.
Savannah: Oh, DFAS instead?
Paige: FUCK YES!
