F-420 meaning and definition

A grossly oversized civilian vehicle, owned by an individual as a status symbol. Named after the Ford F-Series, but actually refers to much larger vehicles. This can be something like an Escalade or a Hummer, but is usually represented by an enormous pickup with nothing in the bed. Not even an obnoxious chrome storage box that reflects sunlight directly into the eyes of other drivers. As the owner/driver generally has no actual need for a vehicle as large as this, he/she must have been high to think that they did. This theory is often exemplified by driver's inability to keep one within the confines of a lane.
