He also screams obscenities in foul torrents, though he usually only does so during the day when neighbor kids (including our young daughter) aren't home. He generally tones it down when they're around, but there's an occasional outburst. But at this moment (I'm working from the kitchen table this afternoon), he's in rare form, screaming "MOTHERF**KER!!! F**K YOU!!!" etc., etc., etc. It sounds as if he's in total rage, tensing every muscle in his body as he yells. I can't imagine that he's not beet red with veins bulging and sweat on his brow. I've never heard any noises that would suggest he's throwing things or that he ever becomes physical when he rages.
I've always assumed there's no one in there with him because nobody ever yells back. By chance, my wife saw the guy's dad at a museum soon after we moved in and all he said was, "I guess you've heard our son." My wife said something like, "yep..." and that was it. The dad offered no explanation.
Is this tourettes? Coprolalia? Are the two distinguishable (I really don't know)?
