L.O.L. Really?

Some phrases said are said so often, everyone in the world should agree never to utter again.  "L.O.L." is one of those things.  It is beyond irritating, old people say it, middle aged people say it, teenagers, children say it and if small rodents could use their little digits to type would also say it.

If people were really "laughing out loud" as often as I have seen it pop up on my computer screen and in text messages nearly every person I know would be on a psychiatric hold because they were delusional and a possible threat to themselves and others.  Every time I read it I picture the writer sitting in a silent environment (their office,  on a bench , walking on a sidewalk, etc.) typing away, then out of nowhere, without any clear cause they burst in to laughter.  Uncontrollable and drawn-out laughter; usually when people start to "l.o.l." it lasts a good amount of time.  Some might say that it is a sign on mental illness......I'm just saying.
