A person who likes talking about themselves excessively and often dominates conversations with self-centered topics is often referred to as a "narcissist" or "egotist." Let's briefly define both terms:
Narcissist: A narcissist is someone who has an excessive preoccupation with themselves, an inflated sense of self-importance, and a constant need for admiration and validation. They often lack empathy for others and tend to see themselves as superior or special.
Egotist: An egotist is a person who is excessively self-centered and tends to talk about themselves, their achievements, or their interests without much regard for others' feelings or perspectives.
Both terms are used to describe individuals who display self-centered behavior and have a tendency to dominate conversations with their own thoughts and experiences, often without showing much interest in what others have to say.
