Originated from BAMF. A GAMF is someone who is more than a badass. Someone who is so fucking badass that when you are standing next to them, you can feel the groady-ness rubbing off on you. A GAMF is someone who over-exaggerates everything ("DAYUMM GIRL, YOU GROADY AS HELL"). A GAMF is also someone who says what he wants, wears what he wants, and drives what he wants.
