Not verbal, but visual, and perfect IMO.... (if a little dangerous/crazy)
today....
driving, bus in front stopping, plenty of room for me to pull out and go past. Signalled, guy in outside lane floored it, determined not to let me out. I made it anyway (he was maybe 40 yards behind and just starting off from the traffic lights, so there was no way he would ever have been inconvenienced), so he proceeded to lean on the horn and then pull up beside me as I was waiting to turn left (him stopping traffic, still leaning on the horn because I refused to look round)
But I could here him yelliing "fucking bitch...." eventually, I looked round -if nothing else to judge whether he was crazy enough to pull out a gun... and he was all "you missed be by this much, you fucking bitch", holding his thumb and forefinger about 4 inches apart.... (bollocks, his headlights didn't even disappear from my vision in the rearview until I was almost past the bus, maybe he meant i missed his ego by that much, but anyway.....)
Well I was all ready to flip him the bird, but I couldn't help myself. he's showing me this 4 inches and so I shook my head and waggled my little finger. He punched my wing mirror (and failed to do it any damage) and drove off. Guess I hit a nerve?
