Slosh brain 

A slosh brain is someone who has a mental disability, or your average person. Unaware of having any manners, drives a low "pimped out" honda civic with a homosexual exghaust pipe that he alone is the only person that thinks it sounds good. A slosh brain also can be used for African Americans that are hypersensitive about their own race, turning anything and everything into a racist remark, slosh brain runs exspecially rampant in female African Americans that think people owe them something, don't hold the door for others, speaks extremely loud for absolutely no reason, eats with mouth open, ignorant to pretty much everything in their life. Slosh brain is also the typical person that doesnt know how to drive, such as tailgating,going 35mph in a 55mph, going slower then traffic in the left lane.

Drake- "That black chick over there is complaining about white water rafting, she thinks it should be called black water rafting."

Lil Wayne- "What a slosh brain.."

Wet-Brain

1.) A person who does a drug (speed/ice) just to put out the impression of something he not, and only acts tough when surrounded by so-called homies who don't like him but it's where everyone meets up to use drugs ended up doing a tad bit much more than what he can handle so now he's all frentic and sketch of those who are really there for him trying to be there for him.

2.)The effect on ones after smoking pot chronic and lasts about two weeks. Being wetbrained causes random intervals of spacing, forgetfullness, stupidity, and occaisonally blackouts.

Ex; Ay remember when our bud connect would hook us up before he was all wigged ouy, "We all used to get high at his crib and smoking up pre-rolls from & watch South Park and now he's all Wet-brain from all the snorting thinking everybody is after him!"
& Yet he's still the only person who supplies you with the best weed around town so you can't avoid him.

Smooth Brain 

A brain that has the quality of smoothness: having an even and consistent surface

Person 1: Wow! Person 2, I am feeling your exposed brain right now, it is so smooth and without wrinkles or blemish. Such a smooth brain!
Person 2: Thank you, Person 1, your compliment is received in a sense of nuanced gratification. I can only imagine the physical ramifications of the immense, sweltering envy you possess as a result of the sheer superiority I display before you, both corporeal and cognitively.

Person 1: Ok, jackass.

Quantum Brain Fart 

is a rule which states that any conceivable thought which ordinarily could be summoned has been lost and has become irretrievable. A complete blank.

He just completely went blank in the middle of the speech. He couldn't say a thing. Musta had a quantum brain fart.
