A shit so large in size that it temporarily blocks your toilet whilst also extending right out of the u-bend and above the surface of the toilet water. Can be facilitated by a bumty
OMFG oh my god. I went to use the lav and there was a giant bog stopper twirling out from the u-bend almost as if it was smoking a giant cigar made out of shit.

When constipated, there is an initial piece of turd that blocks the rest from coming out. Once out, it is easier to defecate.
Once the bogstopper was out, crapping was fun again.
