smiling to myself. smile to myself. smiled to myself.

The phrase LOL needs a backup or another option. It has been so overly used that it doesn't usually pertain to the original meaning. Most of the time when someone says or types lol they are typically just smiling.

This phrase would be used more or less as internet slang.
