Definition & Meaning of "mullethead"in English

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

"Mullethead" is a slang insult that appeared in English in the late 20th century, originally combining "mullet" (a hairstyle associated with negative stereotypes) with "head" to describe a stupid or foolish person. The term uses the hairstyle as a visual metaphor for poor judgment or low intelligence.
