The Jittleyang and Fuhuhluhtoogan meme stems from a series of viral TikTok videos featuring nonsensical, phonetically chaotic names used to describe different moods or 'auras.' Created by content creator @jittleyang, the trend involves a split-personality dynamic where Jittleyang represents a more standard or approachable version of a person, while Fuhuhluhtoogan represents an unhinged, 'final boss,' or demonic alter-ego. The trend became part of the wider 'brain rot' internet subculture, characterized by absurd humor and phonetic wordplay that resonates with Gen Z and Alpha audiences. Users utilize the template to compare two extremes of a situation, person, or character, often using distorted filters to emphasize the Fuhuhluhtoogan side.
