脱了胸罩你没沟脱了内裤你没毛

This name, literally translated, has rather vulgar connotations. It makes light of intimate apparel not creating physical attributes, essentially pointing out that the chest will remain flat when bra removed, and pubic hair would appear only after removing underwear. Such a nickname could serve as casual teasing or jesting among friends and may be offensive in most contexts, so its use should be treated carefully considering cultural backgrounds and situations.
