A food, in the soul food family. Name comes from "chitterlings", IIRC; "chitlins" is the Southern derivative. It comes from the pig - which part of the pig, I don't know. I'm afraid to ask. Lingering childhood memory: I saw a bucket of chitlins defrosting in a kitchen sink - it was something out of a horror movie, Doc Frankenstein's repository of surplus brain tissue or something.
