Akin to pregnancy brain, crossfit brain occurs after an intense crossfit workout. Symptoms include memory loss, disorientation, extreme increased appetite, and flashbacks of the workout.
I can't remember where my favorite quarterback, Russell Wilson went to school. It must be crossfit brain.

Get the crossfit brainmug. An idiot to the infinite power. Someone so stupid that even being in their presence can make you stupider. Worst part about a brain slug is that they don't know how stupid they are/sound. They may often use large words to appear smart
Warning....If you are in the presence of a Brain Slug don't engage them in an argument, and/or a conversation JUST LET IT GO.

Reggie: For 20 pts what is 10x1?
Brain Slug: Well seeing as they can be reciprocals of one another I'm going to change the problem into what is 9x2 which the answer is 18
Reggie: What you've just said is one of the most insanely idiotic things I've ever heard. At no point in your rambling, incoherent response was there anything that could even be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

Get the Monkey brainsmug. the term used by famous people (and normal people) to justify doing something really stupid that if they'd taken half a second to think about it they probably wouldn't have done it anyway. it's a cheap way of saying sorry for doing something dumb and not taking any slack for it.
