The clip comes from Strange Brew, the 1983 comedy film built around Bob and Doug McKenzie, the Canadian brothers first popularised on SCTV by Rick Moranis and Dave Thomas. Their beer loving, hoser personas made belching part of the act, and short excerpts later circulated online as shareable reaction audio. On soundboards the burp survives apart from the film plot, reused by fans of eighties comedy and by creators who need a recognisably theatrical belch rather than a realistic sound effect recording.
