Sophomorically

Acting in a way that is characteristic of a sophomore; immature, conceited, and pretentious, often displaying a sense of superiority and lacking in real understanding or experience. This can involve trying to appear clever or intellectual while making obvious mistakes, using overly complicated language, or showing a lack of genuine depth or insight. It often reflects a transition phase, where one may feel a sense of knowing more than they do, due to their increased experience. The behavior also involves being arrogant and naive.
