bumach

What happens when an obese person's stomach has shrunk and expanded enough times that two crescents of flabby flesh hang down, creating the illusion that they have a pair of buttocks up front.

That is a tremendous bumach.

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!!
