Balloon squeaks have long been a staple of slapstick comedy, where the sound of escaping air signals something losing power, going wrong or falling flat. Online, the same effect moved onto soundboards and short-form video, where its resemblance to a cartoon fart made it a quick shorthand for embarrassment and failed attempts. Because it needs no dialogue and reads instantly, creators keep reusing it for pranks, reaction clips and silly edits, and it remains popular as a simple, instantly recognisable comic cue.
