Autovile

Any person who has spent enough money on a car that he/she becomes unbearably prejudiced whenever conversing about cars.
Alternate: A person standing alone being an absolute jerk.

I find that, at parties, when I try to talk about various great cars that an autovile will inevitably steal the conversation by claiming he has tried them all and ended up in an audience} so privileged that I have to leave, lest I have to give him an expunation of my disgust.
