BAMF

A Bad Ass Mother Fucker.

You must be super hardcore or super cool to get this nickname. Often times when something awesome has just been done by someone, you can yell out something like "Man, that guy's a BAMF!"

Watch the movie The Warriors.
They are hardcore BAMF's.

"Holy shit! Nick Rodriguez just hit that guy in the face with a wooden bat!"
"Yeah, he's a BAMF."
