Pig intestines. They smell like shit even after they are cleaned and cooked. They will make your house smell like shit, your hands and body smell like shit, and your breath smell like shit.
I can't tell you what Chitterlings taste like because I couldn't bring myself to eat something that smelled like shit.
Steve: "I heard Herb's wife left him because his breath smelled like Chitterlings"
Frank: "Whew! That's some smelly shit"
