Doing work, then deciding to procrastinate by do something else, then deciding to procrastinate that by doing something completely different. This keeps on going until you hit a stage where what you are doing makes no sense and isn't useful to you in anyway.
Dude 1: Hey how did the essay writing go?
Dude 2: Well at first it went well, then I decided I should probably revise for my exam first, then I thought maybe I should clean my room so I can revise in a clean environment. However while cleaning my room I got preoccupied with a spider I found under my bed. In the end I hit 'procrastination limbo' when I realized all I'm doing now is watching a spider trying to eat a piece of cheese I laid out for it.
