Bad Ass Mother Fucker. Someone who most likely drives a CT 2004 and is down for pretty much anything. Inspired by that silly bitch Dane Cook.
A BAMF (for instance) would not drive a Hummer 2.No because too many people already have those. They would drive something ORIGINAL. Like A cement truck with custum rims and padding in the back where friends can roll around in. That is a true BAMF!
