Short for 'Fantasy Slut League' - similar to a Fantasy Football League except you draftreal people and are awarded points for 'documented' sexual encounters with them. Frequently organized by high school males without informing the female draftees.
League Member: I had a three-way with two of my draft picks this weekend. *shows phone pic*
League Commissioner: Encounter is validated and I award you +24 points, making you the FSL points leader.
