Finnish bidet

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)

Bertha didn't wipe her ass after taking a shit in the her outhouse in the middle of a blizzard, she just Finnish Bidet'd it
