Don't be a duca, XYZ your pants.

I'm not surprised she tripped on the curb, she never looks where she's going. She is such a duca.

You didn't bring the sleeping bag on the camping trip?!? That is a very duca thing to do.

Is that a horse? Whoops. No. It's a fish. That was obviously wrong. I guess I duca-ed that one.

Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

That smooth brain is dumber than a pile of shit.
