New definitions of abbr that i discovered from people around me… quite interesting i must say!! 🙂
LOL – no, its not laughing out loud around here…. the 1st time my sis used this with my uncle, it meant Lots of Love and remains so….
WTF : this was hilarious…the other day when mom was sitting with me, she read a tweet that ended with WTF.. and was wondering “Why does that person say Wednesday Thursday Friday”at the end of their msg? and its only Monday today!! … 😉 
FML – Was at a friends place, when his 10yr old old niece came over and was randomly reading out stuff from her computer and when she came FML- she said “For my love”…. [why dint i think of that?? ;o)] 
Best of the lot is BTW — new definition discovered by a friend of mine over a phone call –“Biatch, Thats Wacko” ,”Box The Wuss” and when she was talking about her ex bf-  maybe he was “Boinking That Witch’…;-)
