Prius Panic 

1. A sudden feeling of intense dread associated with the Toyota Prius hybrid automobile.

Owners of the formerly chic enviro-friendly car now live in fear that their vehicle will suddenly accelerate out of control, propelling them over a cliff.

2. The scourge of the Toyota PR Department. Whether true or not, millions of people now believe that the Prius is a dangerous car.

"My wife insists on driving my old Chevy Mailbu to work now. She's got a bad case of Prius Panic."

Man 1: Oh Christ. I hope this asshole turns. I'd like to make it home before fucking 9.

Man 2: No kidding. Never seen a Prius go the speed limit.

Man 1: Yes! It's turning! *prius slowly comes to a full stop and turns slower than a fucking Amish carriage*
