New Best Friend. Pretty much what it says on the tin, this one. Everyone (nearly everyone) is interesting when you first meet them, although the gloss can quickly wear off once you get beneath the surface. This is expecially difficult to deal with if you have since married the person. Be wary who you make friends with, and be especially weary if they act like stalkers.
I like him, he is my NBF!!

Natural Bitch Face. The face of someone who naturally looks pissed off as you see them walking around or performing an idle action. You may think they are having a bad day, but that is just their natural facial expression.
Jenny: Did you see Dilon today? He looked so pissed off for some reason.
Melanie: Naw he's fine he just has a NBF.

Not Being Funny. A state of sincerity, where you're so illiterate that the only way you can express how sincere you are is by highlighting how insincere you aren't. In acronym form for efficiency purposes, to be used largely in written communication i.e. msn, text, email, law exam
"nbf, but if i don't get into university heads will roll."
"nbf, but just because you like anal sex doesn't mean you need to tell everyone."
