Runner's Brain

A temporary reduction in mental capacity due to having recently run several miles.

After my run yesterday, I spent half an hour wandering around the grocery store trying to decide what to eat for dinner, only to remember that I had just gone to the grocery store that morning. So then I went to In-n-Out. I think I'm coming down with a case of Runner's Brain.

floating a brain

One "floats a brain" by pulling your testicles out of the fly hole of your pants and proceed about your normal business without acknowledging the exposed genitals. This is typically done in bars or at parties.

I floated a brain at the party last weekend. I will be floating a brain this evening at the social function.

brain sliver

an annoying song that is stuck on a loop in the brain brain that is nearly impossible to make it stop playing.

I woke up and this brain sliver just keeps playing over and over an I can't remove it from my brain.
