When you lock yourself in the bathroom with the water in the shower running to point it's boiling hot. You try your hardest to take biggest shit of your life so you can sweat more and lose as much weight as possible.
I need to drop 10 pounds this month so I'm going to head into the turtle aquarium twice a week.
When one enters the bathroom, turns on steaming hot water in the shower and proceeds to take a shit. The shit particles cling to the water vapour in the air creating a dense stench. For maximum effect, empty all the water out of the toilet so your turd is only hitting porcelain. Proceed to call a significant other into the bathroom, citing you need help with something, and relish their reaction of having to smell your airborne vaporized poo particles.
