I assume FWY is an abbreviation for ‘fooie’. According to Google, ‘fooie’ is a misspelling of the word ‘phooey’ which is “an informal American English interjection used to express contempt, disgust, disbelief or mocking disagreement, similar to saying ‘Nonsense’ or ‘Balderdash!’.”

I wish there wasn’t a detour. I always like to get to phooey straight away.
