FIB

FIB - Friend In Bed

A cleaner and nicer way to say to say fuck buddy for the terminally polite. So clean you can say it in front of Grandma.

First used by Requiem in Danse Macabre of the Anita Blake Series by Laurell K. Hamilton.
Dude 1: Whats the deal with you and Julie?

Dude 2: She just my FIB.

Grandma: Fib?
