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).
Nadia: I think I caught an STM on Facebook yesterday, some new "NutLiquor" vodka that was "69 proof" and had "no salty aftertaste"
Evil power-hungry, strike happy people who derive pleasure from providing mediocre transit service, shabby customer service, and squeezing as many people into a bus (at least 100) as they can (Routes 80, 139, 505, 535). www.stm.info
Damn it! I missed the 139 again! The next one is gonna be jam-packed, and it's gonna take me 30 minutes before I get to the Metro! And then the Metro is gonna be jammed! DAMN YOU STM!!!
STM is slang for smiling to myself and is very similar to abbreviations like LOL (laugh out loud) and FTW (For The Win)It is one of the fastest growingly used words and next year will be added in the English dictionary.
Oh, and it is often mistaken for STI or STD (sexually transmitted infection/disease)
