Noun. A log of feces that contains undigested corn. It is consumed in the same manner that a person eats corn on the cob; the kernels are picked from the feces by one's mouth/teeth. Because corn isn't digested properly, the potential for thirdhand and fourth-hand corn on the cob is also very possible.
