look up any word, like dirty sanchez:
 
1.
A person with a oversized head. (sean severtson)These kinds of people think they are superior to all creatures, but in fact just have a watermelon sized head. With all their body tissue going to their dome, their brain is lacking tissue, and is very undersized, sometimes resulting in doing very stupid and irrational things, like buying oregano from a drug dealer, or bringing a pocket knife to their school.
"Holy shit that guy has a knife!"

"Oh damn, look at the head on that sucka!"

"That must be a Ginormadome!"
