Shit My Pants. In rebellion to the absolute overindulgence of LOL in texts, twitter, email, facebook etc, SMP is to be used in its place... If people were laughing out loud as often as they use the term there would be no war, the world may in fact end because no one would be doing anything but laughing out loud. Therefore SMP is to replace LOL. And only to be used if you are in fact shitting your pants.

Abbreviation for "shit my pants" or "shat my pants." Can be used in a variety of situations, most notably whenever something's funny, shocking or horrifying. Also appropriate when referring to an attractive member of the opposite sex. Whenever it's unclear whether a situation is, in fact, funny, shocking or horrifying, it's best to use a qualifier, e.g. "that was S.M.P. hilarious," or, "that was S.M.P. tasteless."
"The lunch lady at the cafeteria is S.M.P. hot!"

girl#1: "What's that smell?"
girl#2: "I S.M.P.'d"

"When Malcolm busted ass on his skateboard, it was so funny I just about S.M.P.'d"

"My mom just about made me S.M.P. when she found me alone with the pet goat."
