Little is documented about the original source of ninjaromy, so the clip is known mainly by the name it circulates under on soundboards. Its life online comes from short form editing, where a recognisable ten second hit can be dropped into many different scenes without explanation. Creators reuse it for stealth jokes, surprise entrances and mock serious ninja moments, and that repeated context is what gives the sound meaning. Shared as a short downloadable clip, it keeps circulating because the timing is clear and the joke reads instantly.
