What is a social PITA?

A social PITA (Pain In The Ass) refers to a person who is difficult to deal with in social situations, often due to their annoying behaviors, negative attitudes, or disruptive presence. They may create conflict, draw attention to themselves inappropriately, or fail to adhere to social norms, making interactions uncomfortable for others. The term is often used humorously or colloquially to express frustration with someone's social habits.
