When one has exhausted all other means of procastination, so sits on the toilet and hopes for a poo to come out and put off doing actual work.
A: This assignment sucks. I've been procastinating...cleaning my room...watching mid afternoon TV...taking the dog for the walk. I better get into this work then.

B: Maybe its time to poocastinate.

A: Hhhhhrr. Yep. That'll work.
