LTM
"Laugh To Myself" - because not everything funny warrants a LOL; also, more suitable form of laughter when at work or the school library where 'laughing out loud' is frowned upon; and, let's face it, LOL is played out and just all-around obnoxious.
Friend - "wut up?"
Me - "nothin. bored at work"
Friend - "at least you have a job"
Me - "LTM"

LTM
Laughing To Myself. A preferable alternative to the infamous "LOL". This term is to be used in text/email/IM forms when one wishes to express that they find something funny but aren't ACTUALLY laughing out loud.
A-You'll never guess what happened last night!

LTM
Laughing to myself

People use LOL too liberally in colloquial online communication. Lots of things are funny but are you literally laughing out loud? LTM is a more appropriate usage
That was kinda funny, LTM
