Definition
A 'wiseacre' is a person who pretends to be wise or clever but is often foolish or annoying. They act like they know everything, but their supposed wisdom is usually superficial or misguided. It's similar to a 'smart aleck,' but perhaps even more pretentious. 🙄 They often give unwanted advice or make pompous pronouncements. The term implies a lack of genuine intelligence or understanding. You could see them as the kid who quotes Wikipedia articles without understanding the context.
