FSL

Fuck, Suck, Lick. Perfect acronym to avoid sounding like a douche.

"Bruh, my girl just invited me over to her house and told me her parents aren't home."
"Bruh, she wants the FSL treatment."

FSL

Short for 'Fantasy Slut League' - similar to a Fantasy Football League except you draft real 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.
