Kernel Skum

Is a term used after eating a big bag of Orville Redenbacher popcorn, when all the kernels that did not pop mix in with the leftover crumbs of popcorn that your body needs to eat because your still hungry, but instead pick up the kernel and bite and get pissed off so you throw it away.

"Bill for fuck sakes don't eat all the popcorn! Save me some I don't want none of that kernel skum."
