An exaggeration of a person's character results in a caricature. While this might help you to remember it's meaning, don't let the spelling confuse you. Character has an "h" but caricature does not. If you're so excited about something that you feel a little out of control, you might seem like a caricature of yourself to your friends. You can use this word as a verb too. Presidents and other prominent politicians are often caricatured in political cartoons.
