Meathead
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.
