petoskey brain

Used to describe an individual that is so mentally handicapped that their brain matter has regressed to that of what resembles a "Petoskey Stone".

With a completely flat and smooth brain (also diagnosed as SBS (Smooth Brain Syndrome), the individual is left only with enough intelligence for basic communication and survival. A Petoskey Brained individual will assume they're much more intelligent than they are and cause stress for those that are around or work with said individual. With no capacity to tell right from wrong or even solve basic problems, their assumptions become their reality, making them some of the most annoying people to exist in the universe.

There is no cure for a Petoskey Brain once diagnosed and any effected individuals are best left isolated in a secure room that the diseased thoughts cant spread or in some cases burying the individuals resolves the situation. Though potentially increasing the likelyhood of what is known as a Petoskey Zombie emerging at the next full moon.

Thurman: Hey, did you hear Ryan still can't even spell his own name correctly?
Merman: Yeah he's had a Petoskey Brain for awhile now.
Thurman: Really? I didn't know he had SBS
Merman: Yeah, smooth brained as they come. Be careful cause he's been known to drool on people.

Naked Brain

Exposing a single testicle through the opening in the zipper in a exhibitionistic manner, usually to another cooperating party. This can become a game where you see who can show their naked brain in the best location (supermarket, restaurant, library), where the most outrageous location wins the game.

Steve and I went down to the Piggly Wiggly on friday night and I managed to sneak a naked brain out near the frozen foods. He then retaliated and got me back over in the produce section.

Bride Brain

A less invasive, but more expensive version of a frontal lobotomy. Experienced by most brides, as they enter a catatonic state which renders them incapable of sustaining any thought or conversation that does not involve cake, caterers, flowers, wedding dress designers, Chinese wedding dress knockoff designers, updo's, hair pieces, color schemes, wedding themes, and personalized M&M's.

Bride Brain symptoms include, but are not limited to, driving erratically because they can't stop staring at their shiny diamond ring; being amused by the resentment of all their single girlfriends, rewinding songs several hundred times while imagining themselves walking down the aisle, and starvation induced bitchiness which is generally followed by late night binging at a Dairy Queen. (Note that this can only occur outside of the bride's native geographic area, where they can't possibly run into anyone they know).

Symptoms are ordinarily well controlled with valium, alcohol and endless hours of watching youtube "first dance" videos.

brain fuck

The condition usually experienced after regaining consciousness after tripping your balls off (using LSD) as your mind attempts to recover. Symptoms include a feeling of general stupidity and the soreness one would associate with having a large phallus shaped object repeatedly shoved into the depths of the cranium, no lube.

Oh, brain fuck.
After dropping that dose last night, my brain fuck makes me feel as dumb as a fucking rock.
20 hits of acid will cause a serious brain fuck.

Rat Brain

When a dude stretches his scrotum tightly to one testicle and displays it. He could put it right next to a sleeping person's face, for instance. You could also just tightly wrap it to two testicles.

Dude, get your rat brain out of my face.
