The term "wise ass" is often used to describe someone who is sarcastic, flippant, or overly confident. There are several synonyms that can be used in place of this term, including smart aleck, know-it-all, smarty-pants, and wise guy. These terms can be both positive and negative depending on the context in which they are used. While some people may see being a know-it-all as a positive trait, others may view it as arrogant and obnoxious. Ultimately, it is important to think about the way that words are used and the impact that they can have on others.
