Sexually Transmitted Marketing (STM). A viral marketing campaign that uses blatantly obvious sexual innuendo to spread itself across the internet and/or social networks, leaving victims of its tasteless imagery feeling almost as dirty as those who catch its biological counterpart (see STD).

A more realistic saying for when someone says something funny over the internet as opposed to lol because no one is really laughing out laughing.
