In some students or online groups, there is indeed a phenomenon of using code words to comment on or belittle others' appearance. These code words may sound obscure, but they often have negative connotations. For example: 1. **"Green"** - used to describe someone who is not good-looking. This word comes from the homophony of "ugly" and "environmental protection". 2. **"Not very natural"** - implicitly saying that the other person wears too much makeup or has plastic surgery. 3. **"Having personality"** - seemingly a neutral word, it may actually be commenting on the appearance of having unique characteristics but not conforming to mainstream aesthetics. 4. **"Mature"** - in certain contexts, it may be used to imply that the other person looks old. 5. **"Cultivated"** - when used to evaluate appearance, it may be implying that the other person is unkempt and looks like a pedant. 6. **"Different"** - sounds like a compliment, but in fact it may be pointing out that the appearance is special and unsociable. It is important to note that using this kind of language can cause harm to others, and students should be encouraged to communicate in a positive way and respect others. Respect and tolerance are the basis of healthy and good social relationships. If you see someone being treated this way, it is very important to support and comfort the person being commented on.
