The difference in definition between "guts" and "*****".

Guts - is arriving home late after a night out with the lads, being assaulted by your wife with a broom, and having the guts to ask: 'Are you still cleaning, or are you flying somewhere?'

***** - is coming home late after a night out with the lads, smelling of perfume and beer, lipstick on your collar, slapping your wife on the **** and having the ***** to say: 'You're next fatty'.
