Could you please tell me the meaning of the expression "pull a boneheaded move" ?
Hello everyone.
I am reading an article with the following paragraph
"How can someone so smart be so stupid? We’ve all asked this question after watching a perfectly intelligent friend or relative pull a boneheaded move. "
I've already tried to find out the meaning of "pull a boneheaded move" on Google but I didn´t find it. Therefore, could you please help me understand the meaning of this expression?
Also I´d like to know if there is an expression (S) with the same meaning, I mean interchangeable as "pull a boneheaded move"?
Have a nice day.

Answer

The term, "bonehead" suggests that the person referred to has no brains and that his head is just filled with bone. So, to "pull a boneheaded move", is to do something that shows a lack of intelligence or to do something ignorantly.
