Boom-Gasss belongs to a long running family of gross out sound effects shared on soundboards and in short video edits, where an explosion is paired with a drawn out gas noise for comic effect. Its exact origin is not documented, so it spread mainly through reuploads and meme compilations rather than a single film or show. Editors often use it alongside a fart with reverb for even longer punchlines. The extended length gives creators time to build a reaction shot, which is why the clip keeps appearing in pranks, gaming edits and toilet humor posts.
このサウンドについて
A loud boom followed by a long hissing gas release sound effect used in meme edits, prank videos and funny fails for an exaggerated fart joke punchline.
This clip opens with a deep, punchy boom that lands like an explosion, then immediately stretches into a long, sputtering gas release that hisses and fizzles out for several seconds. The contrast is what makes it funny, because the first hit sounds serious and dramatic while the follow through is completely ridiculous. It turns a normal moment into a cartoon style accident, making a character, object or scene feel like it has suddenly lost pressure. Viewers instantly read it as a gross out gag, even without any visual cue or dialogue to explain it.
