-uckle head

Saw this quote from yesterday's Trib:
“I manage a bunch of knuckleheads on a daily basis,”
Here's the article from which it came.

I've just always liked the word knucklehead. It's fun to say.

I looked up it's origin (because i'm geeky like that) and found this:

"knucklehead," meaning a stupid or slow-witted person, is classic US slang dating back to the period of World War II. Apparently "knucklehead" arose as a variant of "bonehead," meaning that a stupid person has a thick skull impervious to listening or learning. (The word "knuckle," meaning the end of a bone at a joint, itself comes from a Germanic root meaning "little bone.") There's some evidence that "knucklehead" was originally military slang.

While "knucklehead" is of relatively recent vintage, a similar term, "chucklehead," dates back to the 18th century, and has nothing to do with "chuckle" in the sense of quiet laughter. The "chuck" in "chucklehead" is the same as "chock," meaning a large block of wood. So a "chucklehead" behaves like a "blockhead" with a head made of thick wood.

Chucklehead is my new favorite insult.
