The information provided below is intended to help you understand some of the cryptic or metaphorical expressions that students may use, and to provide a reference for you to identify and respond to such situations. It is by no means intended to encourage or promote any insulting or hurtful words. Language is constantly evolving, and specific vocabulary and expressions are often influenced by region, group culture, and the trend of the times. The examples listed below are only for academic and phenomenon analysis references. In actual situations, students may create new expressions based on current Internet buzzwords or local characteristics. For example, someone may use some expressions that imply "mediocrity" or "lack of characteristics". Common expressions include: 1. Using "wooden board" or "board" as a metaphor: • "Board face": implies that the other person's facial expression is dull, lacks vitality or three-dimensionality. (This expression usually uses the object "board" to give people a rigid and lifeless impression, and metaphorically means that the appearance has no soul or characteristics.) 2. Using "tofu" as an association: • "Tofu face": sometimes used to describe a face with unclear lines and no three-dimensionality, which makes people feel too soft and dull. (Such expressions imply "lacking features" or "easily overlooked.") 3. Regarding "ordinary" or "rustic": • "Tubie": In some contexts, this word is not only used to describe rusticity, but may also extend to the total negation of appearance, speech and behavior. (This word is often seen more in spoken language and online language, and contains derogatory and unpleasant meanings.) 4. Generally refers to "ordinary": • Use words such as "ordinary" and "ordinary as ordinary" to implicitly convey that the other person has no "highlights" or "attractiveness" in appearance. (This expression often seems objective, but it is actually a euphemistic negative evaluation.) It should be noted that: ① These expressions are often subjective evaluations of the speaker, and different people, different groups, or even the same group may use a variety of creative metaphors in different occasions. ② Between students and teachers, such obscure expressions may sometimes appear in teasing, ridicule, or even malice. If you find that this kind of phenomenon affects the relationship between teachers and students or the teaching environment, it is recommended to properly handle it in combination with the school's rules and regulations and communication channels. ③ Understanding this kind of language can help you capture the potential disrespectful information in the language and provide a basis for subsequent communication or psychological counseling. At the same time, you can also consider taking this opportunity to discuss with students the analysis of online speech and multiple values, so that they can more clearly understand the harm that language may cause. In short, there are many obscure and creative insulting languages on the Internet and in the youth group. The above examples only describe some common types and expression ideas. I hope this information can help you understand the current language environment, and at the same time remind everyone to pay attention to civilized communication and jointly create an atmosphere of respect and mutual trust.
