What about okra?

Okra is a vegetable, but it's as disgusting as some of the things you've listed there! People here in the American South love this stuff, but as you pointed out, these folks eat chitterlings too. Okra is green and vaguely pod shaped. It has a remarkably mucous-like texture AND hair. People deep-fry it, they pickle it (which is espeically vile!) and they cut it up to use in soup and gumbo and that kind of thing. They love it, in all its hairy and slimy splendor. Bleah.
