Top Definition
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.
