LBF
Stands for "lower bum fat". LBF is the portion of ass-cheek visible when girls wear short denim shorts, otherwise known as denim underwear.
Girl 1: I'm wearing my new denim shorts today!
Girl 2: Yeah, but your LBF is showing, they're more like denim underwear.

LBF
"Lance Bass Faggot."
An acronym that pokes fun of the recent outing of Lance Bass, the deep-voiced member of the defunct boy band *nsync. This phrase is most commonly used as a joke among male friends, and can be compared to phrases like "fairy", "pansy", "fruitcake", or even "gaylord." Why just call your friend a "fag" when they can be an LBF?
Man, Pete is too chicken to go talk to that girl. What an LBF.

C'mon, dude, you can take another shot! What are you, an LBF or something?
