A child, usually under the age of twelve, who possesses qualities of Cornelian nature. Such qualities include a bowl haircut, horridly pale skin, ugly glasses, awkward posture, disgusting childlike habits, and the occasional doodoo that protrudes from the rear.

Look at the Cornelius over there with Oreo cookie crumbs around his mouth smiling at Prudence across the room?

Wow, you can see a perfect outline of that Cornelius' butt through his overalls ski pants.
