In various cultures and contexts, people often use euphemisms or "code words" to express certain opinions that may offend others. For a sensitive topic like appearance, some people may use more obscure expressions. However, it should be noted that using such language may affect interpersonal relationships and personal feelings. It is recommended to communicate with others in a more respectful and inclusive way. Here are some code words that may be used to euphemistically talk about poor appearance, but please use them with caution: 1. **Face features are regular**: Sometimes used to describe a person with plain appearance, but there seems to be nothing particularly outstanding. 2. **Unique personality**: When talking about appearance, it implies that the person has a unique style that may not conform to the general aesthetic. 3. **Inner beauty**: Emphasizes a person's excellent character or qualities rather than appearance. 4. **Very distinctive**: Gives a vague positive evaluation, which may sound like a compliment, but the specific meaning is unclear. In any case, instead of evaluating others' appearance through hints or euphemisms, it is better to focus on others' strengths and inner qualities. Everyone's beauty is unique in its own way.
