flying brain

This is a favorite trip toy of mine. One would take a single piece of newspaper, forming a ball with air in it and twist the bottom. Then, one light the twisted up part of the bottom and the ball will fill with hot air and rise. As it continues to burn, the ball, now the brain catches fire while floating high abovet and it looks like blood vessels in a brain pulsing with light. Pretty damn trippy!

When playing with with a flying brain, you should probably have some water close by dude......whoa man thats trippy!

deer brains

this is when your doberman or big dog goes insane. Usually a she, and will amaze you of how stupid she is. She can also cuddle in a weird way, by taking up the whole bed. And slobbers everywhere. And has a dent in there head. Physically and mentally.

" Oh my god what is wrong with your dog?!"
"Don't worry about her, she has deer brains."

Marble Brain

A close reference to "Waterhead" or "Smoothbrain". A "Marble Brain" is typically a just a stupid person with cognitive skills of elementary school kid. Every thought or response is simple & incoherent. Furthermore, it is believed a "Marble Brain" loses a single marble trying to repsond until all their marbles are gone. This is followed by rambling & annoying trailing sentences.

Wow, the retard with a hockey helmet and a bail bonds shirt looks like a Marble Brain.

teen brain

Teen brains are the kind of brain that you once had during the onset of puberty until as late as your 20th birthday. This kind of brain makes the newly sexually active teen seek emotionally charged activities, thus increasing risk-taking behavior. Furthermore, MRI devices has also revealed that while the adults were using their prefrontal cortex to understand the expressions, teens were using their amygdala. The amygdala is responsible for inducing emotions and impulses, not logic and rational reasoning. In conclusion, while it is true that the size of our brains doesn’t change much beyond our 6th birthday, its under-the-hood workings are not done developing until the age of 25.

During my teen years, my brain was all about impulse and emotion; I often made decisions based on how I felt instead of thinking them through—classic teen brain behavior!
