Sonic the Hedgehog is a long-running video game character created by Sega, known for speed, attitude and a confident, mischievous personality that made him a natural fit for internet humour. Short laugh clips like this one circulate widely as reaction sounds, because they need no explanation and work in edits, streams and short videos. Their appeal has lasted because the laugh is instantly recognisable, easy to drop over a fail or a comeback, and flexible enough to suit gaming clips, pranks and everyday jokes.
