Definition & Meaning of "meathead"in English

What is the origin of the term "meathead" and how is it used?

"Meathead" is an English slang insult that appeared in the mid-20th century, combining "meat," implying physical bulk or flesh, with "head," suggesting the mind. It conveys the idea of someone who is muscular but intellectually dull, emphasizing stupidity, simplicity, or lack of common sense. The term is used in informal speech, often humorously or disparagingly, particularly in the U.S. It is mildly to moderately derogatory, targeting intelligence or mental sharpness rather than being deeply offensive.
