Bumchunder

A Bumchunder is any anal excretion that looks remarkably like a type of food. Usually peanuts, sweetcorn, carrots etc

However depite the aforementioned bumchunder looking like food, it is inadvisable to consume bumchunder, as this action may result in "Mouthpoo", or actual chunder if you prefer.

It looked like sweetcorn glued together with chocolate, it was a total bumchunder!!
