Creep aka creeper. Great at carrying on a conversation about himself. Is easily bored to death should the topic switch to you or to someone other than himself. Sometimes narcolepsy may even ensue due to his lack of interest. He is full of it. Full of shit, lame excuses, lame stories, and is plain full of bull.
My Sister: Armondo's on the phone!
Me: Tell him to go away I don't have time to feed his ego today!
My Sister: "Armondo, I'm sorry she's busy right now."
