Definitions by Dr. Dentatus

asscar driver 

Noun - A person who tail gates and switches lanes as if they were racing in NASCAR, except they are driving on city streets and freeways right on your ass. This is one of the only ways to crash your car while traveling in a straight line with other people who are also traveling in a straight line.

This guy is so close behind me I can't even see his headlights. Damn asscar driver.
