Being a BAMF = The act of bringing ones index fingers above one's mouth in the form of a moustache, thus becoming a BAMF
Mitchell Davis/livelavalive: (brings fingers up to mouth, making moustache) I'm a bamf. If you're doing this right now, you're a bamf. Who says that word? I just did."
a word usually used by white nerds to seem cool, because all they do all day is stick tootsie rolls up their hershey hole and play WoW and xbox 360 live
