dictionary

So I was just wondering if there is like a dictionary or list of some kind of what abbreviations and terms y'all use. I know what floosy and flass are, and I definately am a flass, and I've pretty much figured out what abbr. is for each family member, but what does the D stand for? Dear? Any hoo, help me out, throw me a bone, cuz I'm blonde and get confused easily. heehee
