Lately instead of JUST flippin the bird, after they come up and hang onto my rear bumper and pass me I match their speed so we're door handle to door handle (sorta) and make a goofy face, or smile like I was an extra in the "Black Hole Sun" Soundgarden video, or I go old school and fire off a finger and a verbal GO.....YOURSELF ASSH*LE! And so.... What's your thing?
