A person in a lecture or class that feels the need to ask the professor obvious questions just to prove they are listening, sits in the front row of class without fail, corrects the teacher on trivial matters, or speak simply to prove their own intelligence to the other students and professor. This person makes every one in the class groan exasperatingly each time they open their mouth, which unfortunately is far too often. It is rare day when you can sit through an entire hour-long lecture without them interrupting.
