Based on Jersey Shore lingo DTF or Down To Fuck. A DTFCON is a conference of people who are down to fuck essentially an orgy. DTFCONs can be found at some really raunchy clubs or house parties or in an back ally or in your own living room.
Point Man: This club is nuts, man. So many women are DTF here.
Wing Man: I know, playa. It's a regular DTFCON up in here.
