SMO

Slightly-Morbid-Observation. Used in place of lol (laugh-out-loud), when some form of humour is intended, but laughter would obviously be inappropriate.
Person A: Oh man, that test just absolutely killed me.
Person B: Me too, it really deserved to be written today on 06/06 at 6 o'clock. SMO.
Person A: Good call man, good call.

Nobody actually knows what the hell this means, but we think it's the act of being mean. Contrary to popular belief, smo is NOT the act of being mean, nor it is "suck my ovaries" or whatever definitions there are.
Smo is just..smo.
Can be used as an adjective, noun, and a verb. All at the same time. That's right.

Osaka- Smo on!
