The line comes from Avatar: The Last Airbender, the Nickelodeon animated series that ran from 2005 to 2008, where a travelling cabbage merchant repeatedly has his cart wrecked by the main characters and their animals. His despairing cry became a running joke across the show, and fans later lifted it into reaction videos, edits and short-form clips whenever something is comically destroyed. It endures because the gag is instantly recognisable even without context, and the merchant's repeated bad luck makes the moment feel both familiar and funny.
