A person(usually and hopefully male) that frequents affliction or hollister stores and local GNC's looking for the latest muscle gainer. Known mostly for their quick temper and lack of coordination while participating in sports other than weight lifting. Meat Heads usually peak in popularity in high school and start declining after sophomore year in college due to either the over capacity of meatheads at the school or he is just a dousche bag. Overall the lives of meatheads are failures due to the fact they're never satisfied with their size.
Dude, lets go to the UND GNC or the mall and buy affliction shirts.
You're such a meat head.
