no-brain moment

When one speaks a thought and immediately regrets it, wishing their mouth had stayed firmly closed whilst being mercilessly mocked.

In the Tough Arms pub...

Me:
Thinks:
"WOW This place reminds me of the sixties"...

Me:
Thinks:
"Fuck. I just had a no-brain moment..."

brain drain guilt

The guilt that comes with leaving your city for a more affluent area after college, despite the best attempts of your professors and others to prevent it.

Paul: "I had this crazy dream last night. I was on trial for planning to move to Chicago, but the jury was made up of my professors. When the judge asked for the verdict, one of them stood up and said, "We have no verdict. We're just extremely dissappointed in him."

Bob: "Sounds like you have a serious case of brain drain guilt bro."

A brain poser highlights the act of "posing" as intelligent. It combines "brain" with "poser," immediately signaling someone who's faking intelligence.
