A person who acts like an idiot or otherwise incompetent person. They usually do things to try to fit in, but do them wrong. Meatheads also have weird habits that they think are normal, but really aren't. Meatheads are generally slow (mentally) and are obnoxious, and sometimes try to act like experts in areas that are usually unimportant (such as racoon behavior or other such oddities). A synonym for meathead is idiot.
