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.

A turd so massive that it permanently blocks the church toilet and causes humiliation, sarcastic comments and eventually a ban from the vicar.
Don't let Andy hire the church hall as he'll unleash another church bog stopper and we'll have to cancel the church fete again!
