描述兩位高中生對於日常生活、流行音樂及電視節目語不驚人死不休的嘴砲見解，任何事情在他們眼裡只有「酷」（Cool）與「遜」（Sucks）兩個分別，不過正值青春期的他們，男女感情跟性愛等話題，才是他們最關心的重點。
Animated MTV series about two teen aged heavy-metal music fans who occasionally do idiotic things because they are bored. For them, everything is "cool" or "sucks." When Beavis and Butt-Head aren't sitting on the couch, they'd try to pick up girls at the local convenience store, slack off at school or wreak havoc while working at a burger joint, where they'd often deep-fry body parts or dead mice for fun. Their conversations are usually peppered with phrases like "butt-hole" and "fart-knocker" that have become part of the cultural lexicon, as well as uncontrollable giggling.
