The line comes from Nickelodeon's Avatar: The Last Airbender, where a hapless cabbage merchant repeatedly has his cart destroyed by the main characters and other chaos in the city. The gag recurs across the series, turning a background vendor into a fan favourite, and the shout became shorthand online for exaggerated loss. Clips of the moment circulated on video sites and in meme edits, where creators reuse it whenever something small goes badly wrong. Its staying power comes from the show's enduring popularity and the instantly recognisable panic in the delivery.
