People often use code names or veiled words to belittle or ridicule others without confronting them directly. That being said, here are some phrases that might be used to belittle or criticize someone's appearance: 1. "**天生丽质**" or "**丽质**" (translation based on the original question) - indicates outstanding natural beauty, however it can also be considered dismissive of appearance, disregarding an individual's efforts or qualities. 2. "**活力四溢**" - might be used to imply that someone's appearance is unattractive, or at least does not meet traditional standards of "cute" or "fashionable". 3. "**冷面女郎**" - a derogatory term that implies that someone is unattractive or lacks charm. 4. "**裸体生子/女**" - a term once used to describe illegitimate children, in some cultures it can also be used to imply that someone's appearance is unattractive, implying inferior genetics or bloodline. 5. "**鼠合之众**" - refers to a group of people who are disorganized, and may imply that these people's appearance is unattractive or disproportionate. Remember that how an individual looks is relative and reflects societal biases. Many of these phrases or metaphors are considered immoral or indecent due to their derogatory or insulting nature. Instead, it is important to respect others and avoid using any phrases that demean or criticize someone's appearance in a way that could cause hurt or prejudice.
