A person who has a head that cannot be distinguished from their chin, thus forming a chead. The fat of the chead has a convex shape, starting from under the tip of the chin to the bottom of the neck like a turkey's. It's likely the chead was invented by the same person who created the cankle, a combination of the calf and the ankle. A person with a chead most likely used to be healthy with a clear distinction between their chin and their head but has gained lots of weight due to many years of eating cheeseburgers, pizza, cheese sticks and cokes; thus forming the chead.
Short for Chuckle head. Someone who is a dullard. Most used in a business setting where intelligent technical folks have to deal with brain dead business folks. The pointy haired boss from Dilbert is the perfect example of chead.
A person with an abnormally large head, particularlywhen the person's head is wider than its height. A good rule of thumb is roughly the proportion of Arnold's head from "Hey! Arnold".
This word is slang for "chode-head", because of the width to length ratio.
"Hey dude, have you seen how wide that girl's head is?"
"Really? How wide was her head?"
"Dude, like she has a chead."
"Wow, that's wide."
