A person who is very self-centered, cares only about himself and his aesthetics and thinks that he's the best at everything. It's also person that lies a lot, a person that cannot be trusted or count on. He is always talk shit about you and trying to make you a bad person and ruin your reputation, such as.. making fake rumors about you, telling things that are true about you and much more.
Vlad "a bad person" (depends, only from my experience, i know there are some very nice people called vlad)
