An enormously muscular guy who cannot hold a conversation about anything other than weight-lifting and protein shakes. Gets upset very quickly when he cannot complete his own sentences and thoughts. Can be found at nightclubs wearing shirts that are 10 sizes too small (if at all). They are by far the most closely related human beings to that of apes, chimpanzees, and other primate. They are evolutionary hindered and are less capable of following directions than my dead hampster.

One who wears cutoff t-shirts, lift weights, and drinks gallon jugs of water. Usually plays football, wrestles, and is very muscular. They tend to have short hair, and frequently wear sleeveless shirts. Drinking protein shakes and shopping at Hollister are also essential parts of the average meathead's day. Meatheads also tend to abbreviate where they live by putting the first letter of the city, and adding *town after. In addition to lacking high IQs, meatheads tend to stereotype things and people completely wrong.
Common meathead responses:
- "Bro let's down this protein shake then go to the gym."
- "Dude that guy has a Fall Out Boy shirt, do you think he's one of those Emos?
- >>Smashes aluminum can on head<<

Rugby Players...of the chav variety. Usually come in all shapes and sizes, and each others assholes. Muscle grows where no man can grow muscle, replacing brain tissue with muscle tissue. Usually taking on the accent similar to a plymouthian or plymptonite, with phrases such as "'ere fock" and "ya cont" which strangely enough translates as "Here Fuck" and "You Cunt." These apes....sorry rugby players are consistently fucking around, and trying to sleaze younger girls (usually aged between 19 and 12) Not only are these meatheads complete tossers, they also have minions (also known as little bitches) who think that they are powerful due to there large ameoba-likr rugby players

In the gym, a meathead is the guy who only does mirror exercises and looks at himself frequently to see his development (imaginary or real). A mirror exercise is for a muscle that you see when you look in the mirror. These are chest, biceps and abdominals, and nothing else.
Go to any gym and you will see lots of guys (meatheads) like this. Hint: They are always in front of the mirrors.
