1.
v. to deny and put aside any feelings you may have that are telling you to take a shit. Broken down into two words we get, procrastinate and poop. Essentially, one is so incredibly lazy that they don't even bother to relieve themselves, procrastinating their pooping habits. Can also be used as a noun: procrastipooper.
Jeff: Dude, did you hear about that one kid in the obituaries this morning?

Steve: Yeah man, apparently he was a procrastipooper and died from a build up of shit in his body.

Jeff: hm, shame.
