(In a geriatric hospital, someone who seems to be a staff was playing a curling with an old woman who seems to be a patient in the hospital.)
A staff : You suck, Gertrude.
An old woman patient : You suck.
A staff : Yeah, I suck so bad I just skunked you. Which means, you gotta eat your pills. It's not my fault you got no game.
Question 1. To me, "you suck" sounds very very rude in this situation. I guess "You suck" is the vulgar way to say "You are terrible at something(in this case "playing game") Right? I want to know if while playing something like a game, they may say this to even older adults? Does sound natural to you English-native speaker?
Question 2. He said "you got no game". What does game mean in this? "Score"? or "ability of game" or "luck of the game"? Which one?
