AOL instant messanger slang.
How many times a day do you typically type the word "lol" when you are not actually laughing out loud? Even if you do this once, you are a liar, you're lying to yourself, and to your friends who think they've made you laugh.
Instead, be true to yourself and your friends, and type "li" which means you are laughing on the inside, and that's all your friends need to hear to know that they still have a half decent sense of humor

LIS simply stands for laughing in Silence. For all of you who have the addicting thing called myspace, use LIS instead of LOL.
