The laugh comes from Arthur Fleck, played by Joaquin Phoenix in the 2019 film Joker, where the character's uncontrollable laughter is presented as a neurological condition rather than genuine amusement. Clips of that performance were lifted for soundboards and short-form video soon after the film's release, especially in edits that frame an ordinary failure or awkward moment as a villain origin story. It remains popular because the sound is instantly recognisable, emotionally ambiguous, and short enough to drop into memes, reaction videos and gaming montages without explanation.
About this sound
Joaquin Phoenix's laugh from the 2019 film Joker, a strained, escalating cackle used in memes and edits for awkward, villainous or unhinged moments.
This is the Joker's distinctive laugh as performed by Joaquin Phoenix, a sound that starts as a tight, painful chuckle and builds into a loud, uncontrolled cackle that feels more like a cry than a joke. The breathing is ragged and forced, the pitch rises and breaks, and the rhythm stumbles instead of flowing smoothly, which makes it sound involuntary and deeply uncomfortable. Hearing it instantly creates tension, signalling that a character has snapped, is hiding pain behind humour, or is about to turn dangerous, and that uneasy mix is exactly why editors reach for it.
