fb

otherwise known as .."from behind"-- meaning to flip over from your back to your knees in order to assume the position of doggy style

*Note*- fb does not necessarily have to be anal. It can be just as hot when it turns into sexy motion in the ocean with the vagina instead

Ryan-"Wanna go fb?"
Kendra-"Oooh babe, you read my fuckin mind! Fuck yeah, Gil, flip me over babe."
