Tony Hinchcliffe is an American stand-up comedian known for sharp roast comedy and for hosting the live comedy show Kill Tony, where quick, cutting reactions are part of the format. Short clips of his distinctive laugh have circulated online as reaction sounds, separate from any single joke or set, because the sound works on its own as a sarcastic response. Editors use it in memes, streams and short videos to signal disbelief or mock amusement, and its brevity makes it easy to drop into almost any awkward moment.
