look up any word, like sex:
 
1.
A car driver that sits behind a slow vehicle (usually a lorry or tractor) and makes no attempt to overtake, usually sitting too close to the vehicle in front to even see around, sat there like an unthinking Zombie.

Usually either old, female, short or just dumb.
Look at that idiot making no attempt to overtake that lorry, driving too close to even see around the vehicle to make use of an overtaking opportunity what a dumbf*ck zombie driver!
