Arataka Reigen is Mob's mentor in Mob Psycho 100, the manga by ONE that began in 2012 and became an anime in 2016. Despite having no psychic powers, Reigen runs a spirit business and relies on tricks like splashing purified salt to convince clients an exorcism worked. Clips and edits of the move spread across anime fandom and meme pages because the performance is so earnest. Fans still use the sound to joke about bluffing expertise, turning Reigen's salt splash into shorthand for confident nonsense that somehow succeeds.
