A person who people think is dumb just because they have muscles. However the weaker people in society have no idea what kind of training and knowledge it takes to become a master physical specimen. Many weaker people say that meatheads are obbsessed with their muscles. Obsession is a word that the lazy use to describe the dedicated.
Meathead= a highly dedicated and smart person who looks for a healthier lifestyle than the fastfood eating video gaming losers that wear their sisters pants.

Meathead is the common name for a species that is believed to be the evolutionary deadend from cross-breeding between chimpanzees and neanderthals. Meatheads may be identified by their physical traits which include abnormally large upper torso and especially large biceps (or “guns”) and low mental capacity. They may be observed in their natural environment "the gym" and typically congregate around squat racks and dumbells. They are often observed carrying gallon jugs of water and protein bars and/or shakes. It is highly recommended to speak slowly, using the most basic vocabulary when conversing with a Meathead.
Meathead1: "Have you tried the new protein powder? It has 51g per serving!!"

Meathead2: "Have you tried the new protein bar? It has 25g of protein!"

A person who achieves greatness through self-motivation, dedication and knowledge of the bodybuilding art. They are looked down upon by the weaker willed, excuse ridden, unmotivated scum of the Earth. A meathead strives to prove the power of the human body and potential dedication of the human mind. They do not demand respect; they earn it.
