A character on "King of the Hill".
yeah man i tell you what that dang ol' Boomhauer man he talks really fast and you can't understand a dang ol' word he's sayin' man dang ol' fast cars an' faster women dang ol' woowee, man...
He is one of Hank Hill's friends. He's a bachelor who dates a different woman almost every week. He is also obsessed with vintage muscle cars.
According to imdb.com, Boomhauer's incomprehensible rapid-fire style of speech was inspired by a call that KOTH creator (and voice of Boomhauer) Mike Judge received from an irate viewer of his first animated series, "Beavis and Butt-head".
