The ppum shotgun sound belongs to a wave of user made meme effects built from onomatopoeia and an over amplified blast, shared on soundboards under loud misspelled titles. Its appeal is the contrast between the silly spoken ppum and the huge impact that follows, a format that spread through short edits, gaming clips and reaction videos. Because the whole clip lasts only a few seconds and needs no context, creators reuse it as a reusable shock punchline rather than tying it to one film, game or character.
