A knobhead on wheels, is the kind of person, who drives round areas, usually with passengers. There are two types of nobhead on wheels. The conservative nobhead- This is the person who drives with 1 male passenger in the front, who usually, has his window down, and a tab out the window, and casually yells fuck off at people he passes. The semi-conservative nobhead- is the person who usually has a bunch of fat sluts, in the back, and a mate in the front. These drivers are usually on their way for a gangbang. The driver beeps their horn, and the sluts stick up fingers out of the back windows.
