It was clear to me as Jacob moped into the door, that he was being a bumchicker, as he through a pitty party about having to go to work.

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!!
