It is VERY easy to turn the air several shades of blue on the road with a rig.
Sometimes a pothole, sometimes a malfunction of some sort.
Most often an "idjit" doing something STOOPID in front of you like stopping short or pulling out in front of you. Been there- got the ugly t-shirt.
As to the source of the four letter vocabulary - I was on a backpacking trip with my Boy Scout Troop and when we stopped for the night one of the boys asked me about my language, or lack of. He said "Mr H., you're a Sailor, how come you don't talk like a Sailor. I thought for a second and replied that there is a time and a place for such language. Right then and in that setting it was neither the time nor the place. But be assured that if one of them was about to do something extremely stoopid and I could not get their attention in a normal manner or somebody needed a verbal boot in the butt I would sure turn the air blue in a heartbeat. He nodded and went off about his business. One of the other leaders, former Army Artillery officer, commented that I handled that quite well. Well, I be a Machinist's Mate who made his living in Engine Rooms, but I'm definitely not the stereotypical knuckle-dragger.
