The act of taking 4 good sized shits in a single 24 hour period. Usually from the result of eating taco bell for the past week, a lot of exercise, or from being a bodybuilder.

The act of defecating, smoking (preferably weed), drinking a beer, and jacking off, all in one bathroom break. Even better when done at work, on the clock.

Taking a shit in each bathroom of your house (minimum of 2 bathrooms) during one day. You get double points if you can do it before leaving for work.
Due to my overindulgence in alcohol and junk food yesterday, I shit for the cycle this morning.

Get the Shit for the Cycle mug.
The specific time within a 24-hour intestinal cycle in which one has to take a dump. Similar to the body's greater circadian rhythm, but specific to the bowels distinct time of excreting.
Ever since I started staying up later, my body has shifted its shit cycle to end around 2am.

When you have to play a road game(poop in a public restroom) and 4 these next 4 things all go right to make it comfortable experience.

1. Cold, clean toilet seat(cold so you know no one has sat on it for a while)
2. You have a nice,easy, clean dump(a minute or less)
3. Single wipe(although you go back for a second just to be sure)
4. No one notices you just took a dump at a gas station, no one knocks on the door or enters to pee or shit next to you in a multi stall bathroom
