Cuphead, released in 2017 by Studio MDHR, built its run-and-gun bosses and platforming levels around a parry move that lets players bounce off pink objects. The slap became a familiar shorthand for that mechanic in gameplay videos, speedruns and edited clips, where a single sharp hit could mark a save that kept a run alive. Because the game remains popular with streamers and retro-cartoon fans, the sound still works as instant recognition for viewers who know the pink-object rule, even in videos that have nothing to do with Cuphead itself.
