Get the Big Brain Momentmug. If you're a (big brainer) then you've most likely experienced a so-called "Big Brain Moment". But to all you low-class MacDonnals workers, a big brain moment is when you get such a good idea, that you just have to yell it, so everyone can hear how clever you are.
Me a highly intellectual: Hey (Brad)
Brad: Ya bra
Me: You know what I just got?
Brad: Nah brah
Me: I just had this really good idea, but I ain't gonna tell you it, because, you're not clever enough to understand my superior brain (Laughs in a high IQ voice), boy oh boy I do like when I get these Big Brain Moments.

Get the Big Brain Momentmug. Brain cell loss moment that can be several things including: Quite possibly the most annoying moment in your life where you become a dumbass for 5 seconds and after that you forget what you were trying to do (like walking into a room and forgetting why you walked in). Watching D.E.I training videos. Talking to a dumbass making yourself a dumbass (it can also work like a plague jumping person to person) until your intelligence kicks back in (which can be never). Trying to think of more definitions for this word. When you were about to watch a video but a short pops up and you watch and try to go back but it's gone.
Mike: *Walks into a room*
Mike: "Why the hell am I in here again?"
Mike: *thinks to himself* "Goddamn it I got Brain cell loss moment"

In the Tough Arms pub...
Me:
Thinks:
"WOW This place reminds me of the sixties"...
Says:
"Hey guys - let's finish our drinks, go to the park and put daffodils in our hair!!!"
Guys:
Mirthful scorn and abuse
Me:
Thinks:
"Fuck. I just had a no-brain moment..."
