TL: I want to put a Weimu in a grinding bowl* and just watch her. I want to put a hard rock in the bottom and watch an infinite loop of her climbing up the sloped [sides of the bowl] → falling → getting scraped and worn away → hitting the rock.[/end TL]
Instead of "suribachi" (a bowl with rough ridges inside for grinding up sesame seeds and stuff), he wrote "surikogi" (the wooden stick you use with the suribachi), but that's clearly a mistake.
