When you're full of crap, and you don't give a shit

Suppose you haven't taken a shit for a while and every time you go to the bathroom your poop does not budge because it is firmly stuck and rock hard. You strain yourself but still you cannot get the turd out and you tear your butt hole while you are crying and trying to push it out. This feeling of extreme pain and not being able to pass shit is constipation and one calls you "constipated".

The Shit don't come out

When there is a huge log stuck in your butt hole, that you cannot remove no matter how hard you try. This is often caused by not consuming the seed full objects. This also may be a sign that you have Ebola.

Being really, really, really stupid or looking very silly.

when you've gotta go, but you're ass says no

The state where taking a shit is hard and it hurts like a mother fucker!
