When I am driving in the car and another driver does something I don't like I don't honk (unless it's really dangerous) or swear or do rude hand gestures. No, I call the person "Buddy," as in "Buddy, are you planning to turn or not?" or "The accelerator is the one on the right, Buddy." (If I can clearly tell the driver is a woman I will say "Lady" instead, but "Buddy" is the go to term)
I didn't realize how much I did this until yesterday, when I was in a parking lot and the car in front of me stopped inexplicably and just sat there. "What are you doing?" I wondered out loud. From the backseat I heard MQ say "I think he's a Buddy."
