Kentucky Splasher
The Kentucky Splasher a.k.a. the "Baton Rouge Bidet" is a personal hygiene technique wherein an individual finishes a bowel movement and promptly reaches their hand through their legs into the toilet bowl and with a cupped hand, splashes water onto their asshole to spruce it up with a clean finish.
Austin had wings for dinner and promptly rushed to the restroom. Unbeknownst to him he was out of toilet paper. Luckily, he was able to perform the old Kentucky Splasher and felt as good as new.
