Word Nuance & Usage

Although originally a derogatory slang term for a belligerent troublemaker, "badass" is now predominantly used in informal speech as a term of strong praise for someone or something impressively tough, fearless, or cool. Because it contains a mild profanity, it should be avoided in formal or professional registers.

Word Origin & Etymology

Coined in mid-20th-century American slang (first attested in the 1950s among military personnel and street subcultures) by combining "bad" (in the slang sense of tough or formidable) with "ass" (used metonymically to refer to a person).
