"ROTFLMAF", I've Heard - But Who Uses "ILICISCOMK"?

The first abbreviation most of you have probably seen if you've spent more than five minutes in a chatroom anywhere on the web, but the second one and many of these others I've never heard of and are as foreign as the Japanese chat exchange above to me. There are many more examples of chat/email shorthand in this large list from NetLingo - The Internet Dictionary.

BTW (by the way), "ILICISCOMK" stands for "I Laughed, I Cried, I Spat/Spilt Coffee/Crumbs/Coke On My Keyboard", apparently, and if you know that, you've been spending way too much time on the internet - go out and do some fishing or something.
