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..."

All bone, no brain

When someone's head/skull is literally filled with inches of skull, and no brain is contained within that skull. Hence, the person's head is "All bone, no brain."

Synonymous to: stupid, idiotic, not intelligent, dumb, thoughtless, ridiculous, childish, adolescent, Reema, unintelligent, etc.

Reema: "I mean yeah I guess I support gay marriage, but I don't want them to get married.... that's weird. "
Abdul: "Jesus Reema you're all bone, no brain."

Reema: "You can read arabic but you don't know what it means? How can you read the quran/a book and not understand what it says??"
Momo: "Bitch it's just like when you read a chemistry book. Damn all bone, no brain. "
