A term given to a person (typically a male) who acts or does something in a "hard-ass", asshole, and/or tough-guy manner. The Billy Badass themselves, of course, do not think they are a "Billy Badass"; the term is usually told to, or directed at, someone in order to poke fun at, or to express contempt for, their prior, recent, or planned excessive or flamboyant actions.

A real 'man's man' type of guy. One who has no clutch in his 1992 Chevy pickup truck but still drives it like he stole it even sliding sideways into a parking lot stopping mere inches from the car of the person he was meeting for the first time ever. Nonchalantly hopping out of the truck as if it were a normal everyday way of parking.
He totally went Billy Badass in that truck!
