These are usually swinging from a pickup, but I'm sure they're attached to a Prius somewhere to give it some “balls.” I don't think I'm in the minority, but if I see these on a vehicle I instantly assume the person inside is a douche bag. Now I may be wrong, but let's break this down. In order to have the end result of hanging testicles from the back of a car, one first must pay money to obtain them. Next, said person has to spend valuable time attaching them. Finally, they must have the “stones” to be associated with them dangling on their vehicle everyday. In closing, nothing says “chick magnet” like a dude with…car nuts.
