This reminds me of when my g/f was texting a friend and she said "LMAO"
he said "what does that mean?"
-- "Laughing ---my bottom--- off!"
and he said " You don't have to laugh at me just tell me what it means!" and this went on for a while.

She also posted something on Myspace from her cell phone and it said "posted from mobile." This same guy asked "What are you doing in Mobile?" (Mobile is a neighboring town here in Alabama, BTW)

Probably funnier if you live down here..
