Quoting Nate Anderson :
The venerable Oxford English Dictionary has long been the definitive reference work on the English language. This week, it lent the majesty of its name to “LOL” (laughing out loud), a shiny new entry which will now join OMG, IMHO, TMI, BFF, and other linguistic "initialisms" in the dictionary. And why not? It's a perfectly cromulent word.Not surprisingly, LOL also makes it into spoken language and literature, which Anderson points out . If someone only knows the traditional meaning of LOL and uses an online medium, it can lead to results that are funny for those who also know the newer meaning. The following message is an example of this and has been posted by a mother in her late 50s [source: reddit].
