Tarantado comes from Filipino slang used to call someone stunned, wild or foolish, and ulol is a similar insult often paired with it in local meme soundboards. This clip spread as a taho vendor style shout, borrowing the loud, drawn-out calling voice Filipino street vendors use to sell taho. As a short meme sound it travels well on TikTok, reels and group chats because the emotion is clear even in under two seconds, and creators reuse it as a reaction to pranks, fails and absurd moments.
