Kuroo Tetsuro is the captain of Nekoma High School's volleyball team in Haikyuu, the volleyball anime and manga series that first reached a wide audience in the 2010s. Known for his confident, teasing manner, Kuroo often laughs when he is plotting on court or winding up a rival, and fans singled out that sharp cackle for its hyena-like quality. Clips of the laugh spread through anime edits, reaction videos and soundboards, where it became shorthand for a scheming or mischievous moment. It remains popular because it is instantly recognisable to Haikyuu fans and works even without visual context.
