a jimmy neutron is a male hairstyle that sticks straight up towards the front of the head in a ridiculous fashion.

Some genius kid who has a shit swirl as a hairdo. Whenever he tries to explain something that is impossible, some gay faggot starts singing, overlapping the conversation. (example: when Jimmy tries to explain how he's breathing in space, the fatfuck Carl starts singing his ass off, covering up what jimmy is saying.) He has a robotic dog that can do anything, from flying like a helicopter to extracting stem cells from it's victims.
It's a plane! It's a bird! It's Superman! Oh, no wait....it's just Jimmy Neutron with that shitswirl hairdo on his head.
