The show centers on two socially incompetent, heavy metal-loving teenage delinquents, Beavis and Butt-Head, who go to school at Highland High in Highland, Texas. They have no apparent adult supervision at home, are dim-witted, under-educated and barely literate. Both lack any empathy or moral scruples, even regarding each other. Their most common shared activity is watching music videos, which they tend to judge by deeming them "cool," or by exclaiming, "This sucks!" (the latter is sometimes followed by the demand, "Change it!"). They also apply these judgments to other things that they encounter, and will usually deem something "cool" if it is associated with violence, sex, or the macabre. Despite having no experience with women, their other signature traits are a shared obsession with sex, and their tendency to chuckle and giggle whenever they hear words or phrases that can even remotely be interpreted as sexual or scatological.
