What does butthead mean?
"Butthead" is a slang insult used to describe someone who is stupid, annoying, or generally unpleasant to deal with. Formed as a compound of "butt," a colloquial American term for the buttocks, and "head," it belongs to a large family of English insults built by attaching a mocking word to "-head" (compare "bonehead," "blockhead," and "knucklehead"). The word is informal and mildly crude, making it a staple of playground taunts, sibling squabbles, and comedic dialogue rather than formal writing. Its tone ranges from genuinely contemptuous — expressing real irritation at someone's behavior — to affectionately teasing among people who know each other well. Although it circulated as slang earlier, the term became widely familiar in the early 1990s thanks to the MTV animated series Beavis and Butt-Head, whose dim-witted title character cemented the word in popular culture. It remains a quick, punchy way to call out foolishness in everyday speech.
