A practice in which an individual deffecates on a toilet seat when it is down, and thereafter forcefully slams the toilet seat up against the opposite wall.
Due to the impact of the toilet seat and the wall, the feces is distrubuted in a circular pattern on the adjacent walls and ceiling, creating an "arc".
First introduced in France during the interbellum period as a reactionary movement against increased bread prices, the practice is gaining in popularity thanks to short video reels published on "TikTok", a social media platform targetted at youth audiences.
