E.F.P.

An acronym for the phrase "easy Freshman pussy". This is often used by high school Junior or Senior (sometimes even people who are graduated form high school) douche bags who are too insecure to bang girls their own age. Many reasons fuel the phenomenon of E.F.P., but it is most commonly because a 17 year-old penis looks gigantic to a 14 year-old.

Guy 1: "Damn, dude... She's kind of young."

Guy 2: "Shut the fuck up: you know I love me some E.F.P."

E.F.S.

Edited For Sarcasm:Used in internet forums, to convey an even harsher subtle form of sarcasm. Maybe directed at an individual or group when modifying a quote or story. Also acceptable, as an inside joke between users on the forum.

Example:
"ZOMG! The obligatory "OMG HALO" post! I'm so cooool anti-conformity FTW!!!"

When Edited for Sarcasm (E.F.S.)...

Result:
ZOMG! "OMG HALO" FTW!!!

e.f. or f.f?

Eat first, or fuck first?

"C'mon, let's go to bed."

"e.f. or f.f?"

"both."

Alleged to be old Navy slang, meaning, "You wanna get some real food or some tail first?" Occurs in _Time Enough for Love_ by Robert Heinlein. When Dora, "The Adopted Daughter," propositions him, Lazarus asks her "E.F. or F.F.?" She answers, "Both," which is in character for her and also has multiple meanings.
