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.

Doom Stopper is an alter ego used by all time arch villan Ilan Gmach. Doom Stopper was know to chronically masturbate while referring to himself in the third person. Doom Stopper mainly terrorized Sante Fe, New Mexico in the late 1920s, after a while he was quickly captured by the local police force. Doom Stopper tragically died in his cell after fifty years.
Wow, that guy's right arm is so much more muscular then his left. I bet he calls himself doom stopper.

A heart Stopper is where you blend a group of energy drinks, generally with a central flavor into a one gallon container and try to drink it without having a heart attack. They generally have a base liquid such as Mountain Dew or Gatorade. A Five Hour Energy is an optional ingredient but highly recommended for the full effect.
"Hey Ethan, wanna make a Heart Stopper?" "You're gonna fucking die if you drink one of those, Anthony."
