Nobody seems to get the point. Flurge (or however it is spelled), in not a word itself, it is an acronym. Just like Milf means "mother I'd to f_ _ k, Flurge also "stands" for something. The trouble is, no one knows, and it is not something to look up in a dictionary. I have been googling too, and so far no luck. Some people are having fun trying to make up meanings, but no one seems to know yet. So far, my guess is that they just made up a word that sounded funny, but someone will come up with something that works.
