The following is an attempt to analyze this phenomenon, but it should be noted that the examples here are only a summary of the expressions that may appear in certain situations. They do not represent the promotion or approval of such behavior, nor are they applicable to all situations. In fact, in different regions and cultural atmospheres, the types and usage of so-called "code words" vary greatly, and these language expressions often carry the meaning of derogation, ridicule, or even exclusion, which may cause harm to the targeted person. 1. Why use "code words" to discuss other people's appearance 1. Concealment and social pressure: In some student groups, directly using obvious insulting language may be criticized by teachers, parents or campus rules. Code words provide a "hidden" expression, allowing speakers to identify, joke, and tease each other in the group while seemingly avoiding the risk of direct attack. 2. Group identity and sense of belonging: Sometimes students adopt some obscure symbols and expressions in order to show their uniqueness among their peers or prove that they are "knowledgeable". This behavior can form an "inside joke" or code within a specific group, enhancing each other's sense of belonging, even if this communication may inherently contain elements of exclusion or evaluation of others. 3. Unintentional imitation and the influence of Internet culture: Various jokes, comments and buzzwords circulating on the Internet make some students feel that using similar suggestive language to make jokes is also a fashionable way of expression. Ambiguous expressions can convey content and reduce the sense of responsibility. 2. What "code words" may say It should be pointed out that the expressions listed below are only for demonstration purposes. In many cases, the specific meaning, direction and intensity of these words are related to the context at the time, the attitude of the speaker and the sensitivity of the listener: 1. Obscure evaluation of body shape: For example, some students may use words such as "thermos bottle" and "meatball" to imply that the other person is fat; they may also use "bamboo pole" and "bean sprout" to describe a thin body. Such statements seem to be relaxed, but in fact they hide evaluations and jokes about body shape. 2. Metaphors for facial features: Sometimes metaphors are used to describe the other person's appearance, such as using "sculpture" and "brick face" to refer to facial contours, or using "melon seed face" and "egg face" to describe face shape. This statement can be neutral or sarcastic. 3. Use buzzwords and online jargon: Online culture often associates some physical features with specific things, such as calling eyes "marble eyes" or "light bulbs" or describing noses as "bridges". Such expressions often use metaphors and hints, making comments seem playful on the surface, but in fact, they hide inappropriate comments on appearance. III. Issues that need attention This phenomenon of discussing others' appearance in code words actually reflects the social pressure, aesthetic standards and inequality in interpersonal interactions faced by individuals on campus. For a long time, such language will exacerbate stereotypes about individual appearance and body shape differences, and even become a tool for bullying and exclusion. Therefore: 1. Everyone should pay attention to respecting each other when communicating and avoid using words and expressions that may cause harm. 2. School and family education should also help students establish healthy and diverse aesthetic concepts and increase sensitivity to the feelings of others. 3. In the context of the Internet and social media, we should think critically about the use of such code words and avoid blindly imitating buzzwords and ignoring the possible prejudices. In general, the use of code words to discuss the appearance of others in student groups is often the result of complex social psychological and cultural factors. Although the specific terms used may vary depending on factors such as region and popular culture, the above examples are only partial representatives, and behind them are issues such as how to express oneself in a group, gain recognition, and avoid direct responsibility. Carrying out positive education and cultivating empathy can help improve this phenomenon.
