bog stopper 

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.

Church Bog Stopper

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!

bogstopper 

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.

My wife left an everlasting bogstopper in the bathroom this morning
