The glitchy cough has no single known origin, which is typical of short meme sounds that circulate through soundboards, short-form video and reaction clips. Its humour comes from applying a familiar digital glitch effect to a very human sound, so listeners immediately recognise both the cough and the corruption. As creators reused it for failed attempts, awkward pauses and exaggerated reactions, it became a handy shorthand for something going wrong in a silly way. Its short length and abrupt ending make it easy to drop into edits without disrupting the timing of a scene.
