Brainer 

My buddy snuck up behind me and startled me with a brainer!

To produce a brainer, wrap your hand around your ballsac and squeeze, your nutsac will bulge out between your thumb and forefinger simulating the look of a brain

Brain Freeze

When you go the the doctor and have a mole and/or other skin legion removed through the process of freezing, and then a girl sucks on your peepee and her lips turn blue from the freezing temperatures.

"I just got a mole frozen off sorry if I'm sesnsitive babe"
"Glug glug glu- AH! It's so cold what the fuck!!!"
"Oh shit you got that post-mole brain freeze."

Brain goes numb 

When you cum to the maximum and cum harder until you cum and keep cumming until you cum and cum very hard and you just keep cumming until everything around just becomes cum

Person 1: Do you like it when your brain goes numb
Person 2: not sure

Brain Drainer

A story that makes your head explode because it could have been over in about five minutes if one or more of the character(s) didn't have an IQ below room temperature.

It can also be caused when a character who is presented as being quite smart does something uncharacteristically stupid, and everything goes downhill from there.

Despite their legendary status, Shakespeare's plays are notorious for being massive brain drainers.

One example is Romeo and Juliet, which could have been over very quickly with no deaths if the two families just communicated with each other.

Another example is Julius Caesar, which would have ended after the death of Caesar if Brutus didn't decide to save Mark Antony because "he can't think for himself," and they didn't want people thinking they were terrorists. Long story short, he eventually found out that was a bad move when Antony suddenly dropped the façade and revealed that he is much more intelligent and independent than he seems.

Brain-thaw 

The lingering headache that occurs when one is outside in freezing cold temperatures for an extended period and then returns indoors where it is much warmer. Much like a reverse brain-freeze, it is usually felt along the temples of the head.

After shoveling outside for a few hours I had such brutal brain-thaw when I got back in the house.
