Taking as much time on the shitter as possible to delay working on another, more important project. When one poocrastinates they sit back, relax and let nature take its course, however long that maybe. The reading of shampoo bottles, magazines and engaging in existential thoughts of life are highly common, even way after shitting has occurred.
I have a 2,500 word essay due tomorrow. I was a third of the way through when I decided to take a dump. 45 minutes later, deep in thought, I realized I had finished pooping nearly half an hour ago. "Damn I sure can poocrastinate" I said. Then I noticed I hadn't read the back of the toilet paper package yet...
Guy: Imma go to the toilet to procrapinate because work sucks.
40 minutes later...
Guy: That's enough procrapination for today. *opens door* Oh crap it's the boss.
Boss: You have been in the toilet for a very long time! You're fired!
"I really had quite a lot of work to do today; probably shouldn't have spent so long poocrastinating and just got it done. Poocrastination is going to get me fired."
