The Bilateral Backside WipeOsaurusRex

When the Big Ass Bowel Movement becomes so wet, watery, and wild, that you can no longer decipher exactly where shit has landed. So you are forced to roll out a big piece of toilet paper and fold it into one extra long piece of paper. Then (crucially) grabbing it with BOTH hands and simultaneously wiping both Ass cheeks at the same time, to ensure all remnants of watery shit are effectively removed from the ass cheeks.

Bookslide

When you pull out a book from a book shelf and the book next to its falls to its side - where the other book used to be- creating a rapid chain reaction that messed up the entire row.
Dude, dont mess up with my bookshelf please, you create a bookslide behind every time you're here.
