Yes, there is a big difference between “guts” and “balls.”
Guts – Arriving home late, after a night out with the boys, being met by your wife with a broom, and having the guts to ask: “Are you still cleaning, or are you flying somewhere?”
Balls – Coming home late after a night out with the boys, smelling of perfume and beer, with lipstick on your collar, slapping your wife on the bottom and having the balls to say: “You’re next, chubby.”
Although the definitions may differ, there is no difference in the outcome.
Both will result in sure death.
