FILF

FILF: An acronym for Fiancee (aka Girlfriend) I'd Like to Fuck or Fiancee I'd Love to Fuck.
This acronym indicates those young, wonderful women we usually meet in our life. In general they're engaged with coeds waiting for the great day of their life: the marriage. Someone else's girlfriend is a terrible turn on for many men: everybody would die for fucking a fresh, dirty girl while she cheats her boyfriend!
