smomn is an acronym for "squirt milk out my nose." used to denote someone who is laughing at the same time drinking milk. this milk would projectile out of said nostrils of such the person that is laughing in that no one would have any clue if this person had not said smomn. this was made in an attempt to deteriorate the use of lol, which is majorly overused now.
