This is a sub-second vocal sting of one stretched, nasal 'boi' delivered in a cartoon voice and tied to Jimmy Neutron. It feels teasing, bewildered and light-hearted at once, turning a single word into a goofy reaction instead of a sharp insult. It spread through meme edits built around the Nickelodeon character, where it became a quick mark after embarrassing reveals.
