This word is a synonym of " fine " but is far superior. It is the best way of ending a conversation, does not come of as rude or too formal, but it still gives the message. It has a slight racist undertone, but that can be ignored! All in all it's a much better way of saying the word fine, and our hopes remain that it will one day overtake the latter.
"Why aren't any of you saying anything? Fyne I'm leaving"
