The art of washing ones rectum with the shower head after dropping the kids off at the pool.1

When you gracefully leave an upper decker, then use the bowl water to clean yourself afterwards.

Sometimes when you take a crap at home, you realize one of two things; 1: there is no toilet paper to be found and no one to get it for you or 2: your crap was so disgusting that toilet paper will be no match for it at all. A "Hillbilly Bidet" is when you forsake the use of toilet paper altogether, get up off the toilet and proceed straight to the shower to clean yourself off.

The act of using one's urine stream to rinse unwanted fecal matter off one's buttocks and anal region and after defecating.

when your taking a big shit, and it hits the toilet water and then, the water splashes your a-hole. (Just like a kid cannonballing into the pool)

When someone uses a shower as a bidet when there is no toilet paper available or someone is too lazy to buy toilet paper.

A term coined by professional shit poster (and Youtuber) Jeff Holiday, a Finnish bidet is taking a shit in the middle of a blizzard, and letting your body heat melt the frost on your ass in order to wash yo ass (Tariq Nasheed style)
