logjam (log-jam) - noun
1) When you defecate and a chunk of fecal matter is pinched off/left behind and you are unable to push this small remainder out.
As a result, when you wipe, you can never get completely clean, because every time you apply toilet paper you push a little bit of the pinch off poop nugget out, re-dirtying your balloon knot
The only solution is to either get lucky enough for a bigger log to come down the pipe and clear the logjam, get in there with some kind of wedging tool (or your finger), wipe until your wrinkled penny
is red and sore, flush it with water, or just walk around with mudbutt
I took a dump and didn't get it all out. As a result, there was a logjam and no amount of wiping could get it cleared out.
