Boys from other schools. Pronounced like beef-o's. Made popular by Tina Belcher on the show Bob's Burgers. BFOS are more attractive since their reputations are unknown to girls from different schools.

Tina: B.F.O.S, boys from other schools.
Linda: What's wrong with the boys from your school?
Tina: I need fresh faces...and fresh butts.
