A former coworker started a startup, and very nearly used it in the name until he was informed of how the UK views the word.
Not Observing Normal Community Exercise
> 1975. Unknown, derived from British criminal slang. Several origins have been proposed; possibly derived from dialectal nonce, nonse (“stupid, worthless individual”) (but this cannot be shown to predate nonce "child-molester" and is likely a toned-down usage of the same insult), or Nance, nance (“effeminate man, homosexual”), from nancy or nancyboy. The rhyme with ponce has also been noted.
> As prison slang also said to be an acronym for "Not On Normal Communal Exercise" (Stevens 2012), but this is likely a backronym.
