If you drive a Toyota Prius, don't be too surprised if on your drive to work today a passing driver tells you to go fuck yourself.
Today is National "Fuck Prius Day," when those who don't drive the fuel-friendly cars of the future -- and think those who do need to get off of their environmental high-horses -- promise to barrage Prius drivers with F-bombs and middle fingers.
The new holiday is, of course, a product of Facebook and it's a lot less sophisticated than you may think: if you see a Prius, you yell "fuck you."
According to the group's organizer, a dirty look or a middle finger will also suffice.
The "Fuck Prius" movement is expanding to the international level, too. A commenter on the group's Facebook page claims to be from Sweden and says "Representing Prius-haters of Sweden, keep on hatin'!"
One Tempe Prius-hater we spoke to tells us she's willing to brave the heat to spread the message.
"I don't care how hot it is -- I'll stand outside all day. I hate those stupid things," she says.
Some of the comments on the group's Facebook page are a bit more direct.
"I own a diesel ran, turbo charged, V-Dub TDI. On a daily basis I say FUCK A PRIUS!!! I hate that damn car," says Julian G. Romero.
