five-knuckle shuffle

A British slang euphemism for male masturbation. The phrase is playfully anatomical — five knuckles referring to the fist, shuffle describing the rhythmic motion. It's used humorously rather than lewdly in most contexts, fitting neatly into British culture's tradition of bawdy wordplay. Frequently heard in lad banter, stand-up comedy, and British sitcoms where direct language would be too crude but a wink-and-nudge euphemism gets the same message across.
