Amir Asghari recently asked a question about mathematical slang. He was "looking for "non-mathematical" terms or phrases that are used to refer to mathematical objects (of any kind) mainly for educational purposes." He defined slang as "a type of language consisting of words and phrases that are regarded as very informal, are more common in speech than writing, and are typically restricted to a particular context or group of people."
I am looking for examples of mathematical education slang, where the terms refer not to mathematical objects but to mathematical education objects.
An example of what I am interested in is "drill-and-kill." A Wikipedia article defines this as "an unhealthy focus on excessive repetition of simple, isolated skills." I first heard this term from a teacher who did not like teaching that focuses on procedures. (I later heard of the more positive sounding term "drill and skill," but I don't know which of the two terms came first.)
Another term that I often hear is "chalk-and-talk," used to describe the traditional way of teaching through lectures. I first heard the term from the teacher mentioned above who used it in a derogatory manner. (However, the Wikipedia article about it currently seems to be in favor of it.)
