GachiGASM and its animated counterpart GachiBASS are iconic Twitch emotes featuring the face of the late actor Billy Herrington. Originating from the 'Gachimuchi' subculture on the Japanese site Nico Nico Douga, these memes gained massive popularity on Twitch via streamers like Forsen. The emotes are typically used to express intense pleasure, satisfaction, or excitement, particularly when high-energy 'gachi' music remixes or bass-heavy tracks are played. While GachiGASM represents a static moment of bliss, GachiBASS is used to signify headbanging to the rhythm. Together, they form a cornerstone of internet subculture, celebrating the exuberant and over-the-top legacy of the 'Aniki' character.
