Laughing Silently Internally . This acronym is meant to take the place of LOL which stands for Laughing Out Loud. It is my belief, and I think I can speak for millions of others, that the acronym LOL is overused and not meaningful. People have overused it as a quick and easy way to say that they find something funny. They are probably not really laughing out loud. LSI is a way to quickly say that you find something funny but being truthful. Now when you say LOL it will have even more meaning.
