I am aware what the abbreviation really stands for, but the way people use it, the simple lol has been toned down to mean "I think that's amusing" or maybe it gets a chuckle out of me. If something really does make me lol, I will either cap it, or up it by using lmao (especially a capped LMAO). It's kinda silly how we misuse some of the abbreviations out there, but... *shrugs* that's the way it is now.
