A Saturday morning shit that nasty bowel movement you often have at approximately 10:00am on a Saturday morning after a long Friday night of partying and drinking. Generally, the Saturday morning shit is induced by a large cup of coffee.
Taking, or, rather, leaving a Saturday morning shit is not a short project. Expect a twenty minute sit.
1. Dude, I can't talk right now, I'm concentrating on my Saturday morning shit.

2. Boy was that Saturday morning shit nasty. I plugged the toilet and the bathroom fan will have to run all day to evacuate the stench.

saturday morning slut- when you wake up after a wild party the next day only to find a trashy slut next to you in the bed. The bed is wet and there is usually a rubber under the sheets.
If you have more drinks than your liver can handle and black out in a Philly apartment then you are most likely to experience a saturday morning slut.
