BSFFA 

Beloit Science Fiction & Fantasy Association. Someone who is a member of the aforementioned group, and as such socializes beyond the group very minimally, LARPs, plays Dungeons and Dragons, Boffs (the game), goes to Ball Room dances, participates in Rocky Horror Picture Show reenactment, and often wears medieval outfits.

Sig Chi - Have you ever seen that girl over there before?
Theta - Never. Judging by her weird outfit though, I'd say she's a BSFFA.

bsff 

Bsff stands for "best suicidal friends forever" it was started by 2 emo friends in high school. It is rarely used yet is good for a friend ship that is always there for each other and understands what the other is going through because they have the same problem

"Those two emo's have to be bsff's, they are always hanging out"
