Sense: noun/1
"Boobs" is the most common informal word for a woman's breasts, used in everyday conversation among friends or in casual settings. "Breasts" is the neutral, formal term used in medical, anatomical, and polite contexts — you would use it with a doctor or in a health class. "Chest" is broader and gender-neutral, referring to the entire front area of the upper body; it is not specific to female anatomy. "Bust" is a more polite or euphemistic term, often used in fashion contexts (bust size, bust measurement). For example, a woman might tell a friend, "My boobs hurt after running," but tell her doctor, "I have pain in my breasts," and ask a shop assistant, "What bust size is this dress?"
Etymology
The word "boobs" likely comes from "boobies" (an old slang term for breasts), which may have originated from the Spanish word "bubí" or the Latin "bibulus" meaning 'drinking' — a reference to breastfeeding. The 'stupid person' and 'mistake' meanings probably came from an older sense of "booby" meaning a naive or foolish person, which itself came from the Spanish "bobo" meaning 'fool' or 'stupid'. The verb sense developed later from the noun meaning 'silly mistake'.
