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.

A loud ppum shotgun blast sound effect used as a sudden meme punchline. Creators drop it over exaggerated hits, reveals and fake shootouts for comic shock.
This clip is built around a single exaggerated shotgun blast preceded by a sharp ppum vocal sound that mimics the shot. The attack is extremely loud and clipped, with a hard crack up front and a brief boomy tail that cuts off quickly. There is no music or dialogue, just the impact itself pushed to meme volume. Played over a normal scene it instantly turns a small action into an over the top moment, which is why viewers read it as a joke about sudden force rather than a realistic gun sound or anything threatening in context.
