Definition

A person who makes conceited, sardonic, or insolent comments; a know-it-all or smart aleck: The term "wise guy" refers to someone who behaves in an arrogantly clever or sarcastic manner, often by making disrespectful or mocking remarks. It implies a lack of respect and an irritating overconfidence.

Usage
