In some school settings, students may use slang or humorous words to describe teachers' appearance, which are often teasing. While these terms may vary by region and culture, here are some common examples: 1. **“四眼仔” or “四眼妹”** - Refers to teachers who wear glasses, with a teasing tone. 2. **“油汁”** - Used to describe teachers who are not very neat or give people a feeling of not being fresh. 3. **“老干部”** - Describes some teachers who dress in an old-fashioned way. 4. **“老巫”** - Some students use it to describe female teachers who dress seriously or have a stern expression. 5. **“土肥圆”** - Used to describe teachers with a plump figure, which may have a certain derogatory meaning. 6. **“大叔” or “阿姨”** - Used to describe older teachers, which may be a little teasing in tone. It should be noted that these terms are usually used in a joking manner and may not be appropriate for formal occasions. At the same time, this kind of teasing may be offensive to some teachers, so these expressions should be approached with sensitivity and respect.
