Brain Fart

A sudden and involuntary (although depending on the source, not altogether unexpected) release of ignorance.

Jeff had a brain fart and locked his keys in his car (again!)

Brainal

the phenomenon whereby the anus possesses it's own brain and makes it's own decisions.

brain + anal = brainal

You are walking home and the urge to shit hits you, the brain in your head tells your anus to tighten and you continue walking. You are doing very well until close to home when all of a sudden you're scrambling for your keys and fumbling to open the door, running to the toilet whilst undoing your pants and just making it in time (or sometimes not making it).

This situation occurs because the brain in your anus overrides the brain in your head. Despite your best efforts to clinch and tighten, your brainal can sense when a toilet is near and immediately starts to open the brown gates.

Wrinkling my brain

A phrase that comes from Troy on Community. It basically means "blew my mind", or a "glass shattering moment".

Annie: Did you know that someone who has already been born could live for 800+ years?

Troy: That's wrinkling my brain!

Booger Brain

Someone who is so stupid, or who seems to get more idiotic every day that you swear they pick out parts of their brain every time they pick their nose.

How can that booger brain not remember what I told her 5 seconds ago? She must have picked out part of her frontal lobe from her damn nose this time.
