It's pretty stupid but a friend wore a Walmart hot dog costume and for some reason everyone thought it was funny, started chanting hot dog kid and he won the best Halloween costume award of that year.
Next year he wore a penguin costume and as he stepped up on stage he ripped it off to reveal the hotdog costume underneath. Everybody fucking lost it. Sadly we have a rule that you can't win 2 years in a row so while he didn't get the prize we all knew who had the best costume that day
That is how the legend of hot dog kid was born at my high school
