Oh and FWIW, most of these are pretty easy to decipher when used in context. But after months of trying, I couldn't get FTW no matter what! I had seen it in countless sentences, used by different folks in different contexts, and just couldn't get it!

Oh, and ICSY is one I picked up from my baby sister. I pretty much only use it on RJ, though. OTOH, sometimes, U13 is also deserving.
