The clip works as a generic slap effect rather than a line taken from a single film or show, which is why it travels so easily between unrelated edits. Online, the phrase this slaps is slang for something excellent, so the sound also doubles as a playful stamp of approval when a clip, beat or outfit lands well. Creators keep returning to it because it is instant, recognisable and easy to understand without context, making it a reliable shortcut for comedy, surprise and light-hearted punishment in short-form video.
