I think this might need some fixing because usually we have to deliberately choose an icon rather than it showing up when we type l-o-l. Since there are several reasons and ways to use l-o-l it wouldn't be good to have this icon pop up on some posts. It could infer we're laughing together or be seen as laughing 'at someone'. I also don't want to have to hyphenate the l-o-l or put spaces.
