Billy Herrington was an American actor and former adult film performer who died in 2018, but his second life online began in Japan in 2007 when clips from his wrestling-themed videos were uploaded to Nico Nico Douga. Re-edited as Gachimuchi meme remixes, the clips gave him the nickname Aniki, meaning big brother, and spread to YouTube and gaming communities worldwide. Editors kept isolating his shouts and phrases as standalone reactions, so the sounds survived long after the original remix videos and still signal in-joke wrestling humour today.
