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"...

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..."
