In northern dialects, “der” is also written as “得儿” or “德儿”, pronounced as one syllable. The meaning varies in different parts of the northern region. In the provinces of Heilongjiang, Jilin, and Liaoning, it refers to being foolish or silly, similar to being dumb or naive. In Quebec, when people speak French with a strong accent, they often pronounce “deux” as “Der”. In reality, it means two. In certain areas like Changchun in Jilin and Daqing in Heilongjiang, “der” can also mean impressive or skilled. For example, if someone has excellent basketball skills, you can say they play basketball really “der”. In colloquial speech, “der” is used to describe someone as kind and good-hearted, with a positive connotation. For example, “喆” represents intelligence, so “Der喆” means someone is incredibly intelligent. “驰” represents running fast, so “Der驰” means someone runs faster than anyone else. “Der爽” is equivalent to feeling extremely comfortable or satisfied. “Der飞” means shamelessly daring or audacious. Therefore, “傻der” means someone who is naive or simple-minded, in other words, a fool.
