As a Registered, Certified Korean™, I have eaten more disgusting things than you can count, more spicy things than you can count, and more delicious things than you can count. The food I most abhor(but can eat a bowlful of anyways, because I'm like that) is a Korean soup composed of spinach, and the inside of a cow's stomach and small intestine. Notice the difference: the insides only. As in, half-digested grass.

What kinds of food repulses you?

I exist! I am a pedant! I have a foreboding signature!
