Obunga began as a distorted face meme shared online before becoming one of the best known Nextbots in Garry's Mod and games inspired by Nico's Nextbots. As Nextbot chase videos spread on YouTube and TikTok, players linked the image with loud proximity audio that grows more intense during a pursuit. That pairing turned the sound into shorthand for an unstoppable meme chase, and creators now reuse it outside the games for surprise entrances, pursuits and edits where something should feel both scary and ridiculous.
