Hello, This is a part of a documentary. Two people are sitting in a bar in an old pirate city and chatting about pirates' favourites drinks. One of them is the bar owner, he gives grog to the other one. The one who is drinking the grog asks: "And what are you drinking?" Bar owner says: "I'll drink rum, too. It's a pass time in a pirate city." I know what "to pass time" means. Also the dictionary says: "kill time, to occupy oneself with some activity to make time pass more quickly:killed time by watching TV." But I'd never seen "a pass time" phrase before. Does it have the same meaning? Like "it is time to pass time in a pirate city." Why does he specifically say "a pass time" as a noun? Thank you.
