Classhole

The one idiot in your class, preferably large lectures, that constantly interrupts the professor with one of four type questions. These questions are rarely honest quests for knowledge, but dependent on the professor's approval. 1. Questions that he/she should already know from reading required texts/materials 2. Questions that are not necessary reading, but easily figured out or looked up in a matter of seconds. 3. Questions designed to show off the asker's "intellect" of knowledge of the subject. 4. Questions that have absolutely nothing to do with the subject. Often, after a period of time, the professor will even go so far as to limit the classhole to a certain number of questions per class.
