It can either be a person with just a very big head or a simple weirdo and then u would call them bighead. Their head is so big all u can do is laugh, call them names and make fun of them. Bigheads are very weird! You don’t wanna be a bighead also because they are very rude weird and ugly. If you know a bighead I would run for you’re life. Bigheads are just bad bad bad people!
Oh my god Becky! It’s a bighead! We better get out of here!”
