Tooru D4C appears to circulate mainly as a fandom audio label rather than a widely documented mainstream quote. The wording strongly suggests JoJo-related usage, combining a character name with a familiar Stand reference, which helps explain why it spreads in anime edits and meme posts. Sounds like this stay popular because they function as shorthand for shared knowledge: viewers who catch the reference understand the joke instantly, while everyone else still gets the dramatic, offbeat energy created by the clip’s sudden entrance.
