I have a friend like that. He uses cussin' like poetry. There is an art to it. "Worthless like [boobs] on a boar..." Stuff like that.
Was the character you played mad, or just colorful?
I noticed this week that cussin' has become more mainstream. I heard two lawyers (not me) use cuss words in court, in front of a jury, and I was the only one who even noticed.
30 years ago, you could call a friend a "son of a [female dog]" and it was a sign of affection. But then it was politically incorrect. I think the use of colorful terms is coming back.
