What would be "A ball that cannot kick"?
It would be written the same but it wouldn't make sense in Korean as the subject for 찰 수 없는 공 is implicitly "noone" as it really means "a ball that noone can kick". I.e. you can think of it as (아무도) 찰 수 없는 공
Yep, I've got two of that type.
Probably a bowling ball
bola que não tem como chutar, bola que não dá pra chutar
