I hardly know anything about 相撲, so I was hoping someone else would butt in with a fun fact. Looking at Jisho this kani is actually usually read as ボク, and one of the words it appears in makes me shiver (not a fan of gory physical violence. I can’t rewatch movies like American History X and A Clockwork Orange. Sometimes the images still float up and make me cringe). So please no 撲殺 for me!
