The line comes from 'Boss of Me,' the theme song for the American sitcom Malcolm in the Middle, performed by They Might Be Giants. In the show, the fast, restless song matched Malcolm's chaotic family life and his feeling of being caught between childhood and growing up. As short clips from TV themes began circulating online, this opening lyric stood out on its own because it sums up indecision in a few seconds. It remains popular in memes and edits that need a quick, recognisable way to say someone has no answer.
