Obtained from a non-swear insult generator, an incongruous pumpkin seed is someone that doesn't fit in due to being small and wide. Like a pumpkin seed.
Me: "You're such an incongruous pumpkin seed."
Incongruous Pumpkin Seed: "That's not true! My mother says I am very congruent..."
Term used for generic white keds-like tennis shoes, especially when worn by someone with big feet, because their shape and colour looks like that of a roasted pumpkinseed.
"They wouldn't let me wear my boots on the gym floor, and I ended up wearing the school's nasty pumpkinseeds!"
