"Truepopperking33" is the user name of an otherwise unnamed youth that challenges Cleveland Brown over his mastery of his favorite snack food, Slop Poppers, in "All You Can Eat".
When they engage in a flame war. to settle things, Rallo arranges to a "Popper-off" at the headquarters to determine the true champion of Slop Poppers.
At the challenge, the rival turns out to be just a kid but a real handful for Cleveland. As things get messy, the company founder Miller M. Greene arrives to tell them both off. And, disgusted with their behavior, shuts down the entire factory, leaving them with just their petty one-upmanship.
"Truepopperking33" is voiced by Max Burkholder.
