William Glen Harold Herrington (July 14, 1969 – March 2, 2018), known professionally as Billy Herrington, was an American model and pornographic film actor. In the late 2000s, his appearances in various gay pornography movies led him to become a popular Internet meme on video-sharing websites such as Japan's Nico Nico Dōga, where he was referred to by the sobriquet "Aniki" (兄貴, lit. "older brother"). Since then, at least 110,000 short mash-up parodies of his clips—known as "Gachimuchi Pants Wrestling" (ガチムチパンツレスリング Gachimuchi Pantsu Resuringu)—have been produced by fans.
