The phrase comes from everyday Japanese, where kinshi means prohibited and ichifun means one minute, so the whole line is a plain, literal announcement rather than a named quote from a known character. Short Japanese voice lines like this circulate on soundboards because they are easy to reuse out of context and instantly change the mood of a clip. This one spread as a niche reaction for smoking jokes and fake punishments, valued less for any original source than for how a strict sounding ban can be applied to almost any harmless habit.
