Best Male Friend Forever
A girl's very close friend of the other gender. She can have more than one, but they are all as close to her as a BFF, so nobody usually has more than one. May or may not be in love with the girl.
Girl one: Stop hanging out with Steve, you hang out all the time.
Girl two: But Steve's my BMFF, of course we're going to hang out.

Steve: Yeah, you're just jelly that you don't have one!
Girl one: *cries*
