Meathead
"Meathead" is a colloquial term often used to describe someone who is perceived as overly focused on physical strength or bodybuilding, sometimes at the expense of intellectual pursuits. The term can carry a humorous or derogatory connotation, suggesting a lack of sophistication or depth in personality.
In popular culture, the term is notably associated with the character Michael Stivic from the television show All in the Family. Portrayed by Rob Reiner, Meathead is the son-in-law of the main character, Archie Bunker, and is characterized by his liberal views and conflict with Archie’s conservative beliefs.
