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.
