Matty Matheson is a Canadian chef, cookbook author and television personality who became widely known for his high-energy cooking shows and later for playing Neil Fak in The Bear. His loud, unmistakable laugh is one of his most recognisable traits in interviews and kitchen videos, which is why short clips of it are shared as reaction sounds. Creators use it to add warmth and personality to food content, comedy edits and streams, and it endures because it sounds spontaneous rather than performed.
