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

an abbreviation for: "laugh inside silently" is intended to be used for instant messaging, an alternative to the abbrev. "lol". Due to the fact that no actual laughing occurs when one types "lol" to another, this term, "lis", enables the receiver of the message to understand the sender's true level of humor
