Get the manjack mug.
A turd so large that it contacts the bottom of the U-bend while still emerging from the unfortunate crapper's anus, causing him/her to be literally jacked up off the seat. There is a particular risk of manjack when using toilets of the curious German or Austrian design, which have the U-bend at the very front of the pan and a shallow "deck" for inspection of stools.
"How long are you going to be in there?"
"Sorry, got a bad case of manjack and I've run out of toilet paper".
