look up any word, like sex:
Bad Ass Mother Fucker - any guy who's remarkably comfortable with his sexuality. he gets "family portraits" taken with his roomates. isn't scraed of a little bromance with the intent of being daringly funny. said roomates, may also dress in slacks and argyle sweaters. maybe even OVER dress to a work function in tuxedos with tails and hawaiian print shirts. they may also have the balls to wear superhero briefs and show them off in public like it ain't no bigs! while out getting drunk, they're not afraid to buy rediculous amounts of "girly" drinks and chug them while chasing said drinks with jolly rancher shots and buttery nipples. these guys are so badass, that some lucky girls might get bought shots of water in a bar. these said BAMFs also have a tendancy to listen to classic songs and may even be caught singing Abba's Dancing Queen at a local kareoke night. also, they might do these things completely trashed off booze, or sober. never know with a BAMF
BAMF - most TACPs and JTACs

*Quotable B.A.M.F. Moments*

"What? This?" Neville dismissed his injuries with a shake of his head. "This is nothing."
"Alecto, Amycus' sister, teaches Muggle Studies, which is compulsory for everyone. We've all got to listen to her explain how Muggles are like animals, stupid and dirty, and how they drove wizards into hiding by being vicious toward them, and how the natural order is being reestablished. I got this one," he indicated another slash to his face, "for asking how much Muggle blood she and her brother have got."
"Blimey, Neville," said Ron, "there's a time and a place for getting a smart mouth."
"You didn't hear her," said Neville.
"But they've used you as a knife sharpener," said Ron...Neville shrugged.
"Neville's the man!"
"We used to sneak out at night and put graffiti on the walls."
"Mandrakes!" Neville bellowed at Harry over his shoulder as he ran. "Going to lob them over the walls--they won't like this!"
"Have you seen my grandson?"
"He's fighting," said Harry.
Someone had broken free of the crowd and charged at Voldemort.
"I'll join you when hell freezes over," said Neville.
With a single stroke Neville sliced off the great snake's head, which spun high into the air, gleaming in the light flooding from the entrance hall...
Some old-school BAMF: "I'm worth twelve of you, Malfoy."

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!
