Wait what?
lol someone said to use it to ask for a phone number with someone you've been talking to.
I've tried it and it usually gets a laugh and the phone number.
Example:
Az333 8/30/2012 5:12:38 PM
Oh no! I lost your phone number! What is it again?
Her response
Lmao u are wayyy too cute.. Omg!! Lol
Shes not a very good speller and she left out the damn number but I'll take it lol. The other times it worked.
