The clip is named after Brutalmoose, the long-running retro gaming channel of YouTuber Ian MacLeod, and preserves one of those tiny throwaway noises that meme audiences love to isolate. As a soundboard upload it travelled the way short meme audio does, passed between meme pages and editing Discords rather than through any single viral video. It endures because the plop is endlessly reusable, sitting naturally beside clips like fart with reverb and goofy ahh sounds in the toolkit of editors who need a cheap, instant laugh.
