Turn the toilet off at the wall, then flushing all the water out of the systern. Then stick an entire industrial role of toilet paper into the dry poo-hole. Then take the biggest stinkiest poo you've ever done in your life, preferably riding the horse backwards and leave the poo just sitting there on the porcelain.
The next person to walk into the toilet is in for quite a shock, and then eventually when they do switch the water back on they're in clog town. Water floats to the top of the bowl, goes everywhere and the poo should float out to freedom.
The act of shutting off the water supply to a friend or foe's toilet (the knob / valve behind the toilet close to the floor) and the flushing the toilet to empty the bowl of all water.
At the point, you push out your steaming turd so that it sticks to the ceramic part of the bowl. It creates a giant mess to clean up. Make sure you are not seen leaving the bathroom as a beat-down might ensue if you are caught.
A common double whammy is to also pull an upper tank or upper decker. This will create total havoc for the toilet & the person that owns it.
Entire commodes have had to been ripped out and replaced because of the devestation this creates.
Jeffrey was mad at his friend Ryan's father. So when he was visiting their home, he used their restroom and pulled a dry dock. He did not have enough dung left though to also pull a upper decker.
At someone else's house, you turn off the water supply to the toilet, then flush it. Now the toilet bowl is empty, no water in it. Now you take a dump, essentially leaving your turd welded to the inside of the toilet bowl. This is "dry docking". The bathroom now smells like an outhouse since the turd is fully exposed to the air. For added effect, bring a jar with a few flies, release them in the bathroom, thereby enhancing the outhouse "feel".
V. The act of turning the water off on the toilet. flushing it, so there is no water in the bowl, and taking a dump. Then, in order to flush it, some one must kneel down by the pooh to turn the water on.
