brain sludge 

Brain sludge is where you have so many intrusive thoughts that it completely derails your ability to think or focus.

I took a test today at school and I had a really bad case of brain sludge.

Long Island Brain Slice 

Slang for a powerful street drug. It is a razor sharp crystalline chemical that you tuck under your eyelid. When it cuts your eyeball open it slips into your blood stream and directly into your brain. The high is terryfing. It takes all your greatest fears and insecurities and gives them teeth and arms, and then it locks you in a room with them from which you cannot escape. There is also a surprise at the end of the high.

You realize the face of god is somewhere inside your body, but you can't find it.. and it hates you.

Just when you can't take anymore.. you poop your mouth.

Long island brain slice is also known as god drug, cuddy cuddy, elmo, cat vaj, and funt.

Late Night Brain Syndrome 

The condition of your brain in which late at night you think of things that make you sad, such as memories with an Ex or just fun times that you wish you could repeat and relive forever.
It also includes thinking of someone you like, but knowing that they don't like you back, or you're too afraid to find out if they do or not, therefore, you will never get to be with them.

Jay: I am sad.
Ashlynn: Why's that?
Jay: My Late Night Brain Syndrome is kicking in. All I want to do is sleep but I can't stop thinking.

brain surgery 

(adj.) Much like "rocket science," this term is used to describe any activity which may seem overly intricate to the average Joe Sixpack.

I asked Billy Bob to program the DVR to automatically record WWE every week. He looked at me like I expected him to perform brain surgery.

Brain Slushy 

The result when a gun is stuck in one's mouth, and fired. A term made famous by 11 year old internet sensation, Jesse Slaughter, and her rant that got her stalked by the web forum 4chan.

"I will pop a glock in your mouth, and make a brain slushy"-Jesse Slaughter
