I only play in a long running home game with a bunch of old guys. We talk all the time. "Dumbass" is the most common word flung at an opponent who beat you when they held a bad hand and sucked out. Interestingly, the name "Dumbass" comes out of one of the stories told at the table. One of the guy's wives taught a kindergarten student with Downs Syndrome. She was a lovely little sweetheart, but when she had an issue with anyone, including the teacher, she would call them "Dumbass".
All the guys found the story funny and started using the term whenever another player ticked them off. All in jest.
After almost 20 years, there have only been a couple of real flareups between players.
