enigma: GFYM means two things. If someone asked Petar "on the record" what GFYM meant, he would say, "Good For You and Me". If someone asked Petar "off the record", it would mean, "Go F Your Mother". I really don't think GFYM should be used in any PR. It's not very professional. There are ways to convey the same point without using it.
