Word Nuance & Usage

While originally referring to an occupational trade dealing with worn-out livestock, this word has evolved into vulgar British and Irish slang for the testicles and an exclamation of frustration; in Ireland, the singular or plural form is also a highly derogatory ethnic slur against Irish Travellers and should be avoided in that sense.

Word Origin & Etymology

Originally attested in the late 16th century as 'knacker' meaning a harness-maker or saddler (possibly from English dialect 'knack', meaning a horse's harness or trappings), the sense shifted by the early 19th century to a dealer who bought old, worn-out horses for slaughter.
