A person who dominates and monopolizes every conversation and within seconds turns the conversation to themselves to brag about things they have done or seen or will do, things that are not notable in any way. Someone who thinks they are smarter than others but they aren't smart enough realize others ridicule them for their ignorant and oh-so-self-important behavior. Someone who pats themselves on the back endlessly.
