While my kids were growing up, I tried to not use language that was too overtly mean, towards other people. (Reading this, they'll all be laughing. They know that as I grew older, I got weaker and weaker in my resolve and some pretty colorful language issued forth from my yap.)
But back when I was a bit under control, in the kid's presence, I called people of questionable smarts "Pudding Heads."
After awhile, I thought that I needed to assign degrees of Pudding Headed-ness, so thus began the classification of "Stirs".
While making a stirring motion over my head, as if I were swishing my brains with a long wooden spoon, I'd say, "Now, there's a 3-stir Pudding Head." They'd laugh. I was then incited to expand on my "comedy" success.
Soon, it got to the point that they all responded to me simply, wordlessly, making the stirring motion. Or, without any motion at all, I'd say, "Two stir!" They'd all know what I meant.
As they grew into adults and we'd be together, I'd get a real laugh watching one of them evaluating a particularly bone-head move on the part of someone by saying, "Dad ... a 3-stir."
Pretty much, we used this code:
1 stir -- not the brightest bulb but amusing to watch.
2 stir -- a demonstrably dumb individual.
3 stir -- award winning stupid.
Then, you might as well take the leap. If you're beyond "award winning stupid," we jump directly to ...
7 stir -- ignorant, stupid, dumb? ... nah, they're beyond description. Why are they breathing my air?
Stay tuned. I'll soon be ranting about some of my favorite people (Houston drivers) and awarding Stir-Stars to their various performances.
