show half ball

Singaporean slang for wearing an outfit that reveals a significant amount of cleavage — specifically, exposing roughly half of the breast. It's a piece of characteristically Singaporean Singlish humour: direct, visual, and anatomically matter-of-fact. Used in casual conversation without much malice, though context determines whether it's observation or criticism. It reflects Singapore's blend of conservative social norms and irreverent street-level humour, where the body is discussed plainly rather than euphemistically.

(Singapore) To reveal a great deal of cleavage.
