STM

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

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)

Nat.: Oh, remember that time with that teddy bear
Jess: Haha! STM :)
