Billy is a fan-created character for Party Club, also referred to as Dead Club, a community project inspired by the music-making game Incredibox. In that fan context, Billy is presented in horror mode as the power chords beat character, providing a heavy guitar sound for fan mixes and edits. The remake version circulating as a short sound clip keeps that idea intact for creators outside the game, who reuse it in horror-themed videos, animations and memes. Its appeal is its instantly recognisable distorted riff, which signals danger and intensity without any dialogue.
