Fistard

Part of speech: noun

Definitions

1. A crude slang insult aimed at a contemptible or despicable person, blending a vulgar punch-related image with a term of abuse
2. An informal, offensive epithet used to denounce someone as a loathsome, worthless individual
3. Coarse slang for a detestable person, used as a derogatory label of contempt in casual speech

Etymology: The word is a slang insult whose exact origin is uncertain. It appears to be a euphemistic alteration of "bastard", with the front of the word probably shaped by a stronger taboo term, so that speakers could hurl the insult without using the full word. Written evidence for this kind of slang is thin, and the dating is unclear, so the origin should be treated as an informed guess rather than a settled history.
