The literal meaning of this word is bending over, but because the scene where the action takes place is usually in a naked bath, the word "picking up soap" now means bursting chrysanthemums, and when picking up soap in the bathhouse, it will be attacked by other same-sex chrysanthemums behind. It means homosexuality and is also used to describe jokes between boys who have a good relationship.
