There is no widely documented source for the Phil Destroy Bellybutton clip, and its low profile suggests it began as a small user-uploaded sound rather than a well-known scene. Its appeal online comes from the same quality that makes many niche soundboard clips spread: a very specific, memorable name that is easy to search for, reuse, and drop into an edit. Creators keep it in rotation for absurd humour, where a short, unexpected sound can carry a joke without needing context or explanation.
