Commonly used to say "laugh out loud", but often not used to say it. People often type this in with out any actual expression, instead they use it as a conversation filler. Also used when you don't want to express how much you don't care about something, as to not hurt their feelings. This is also commonly used when your not paying attention to what the person is saying. Or they say something really long, and you don't want to read it. This description, for instance.
