Standing outside the MTR station while smoking and playing with your handset is so MK"
You pronounce and say it the way that the M is not pronounced like the alphabet, but the way it would be pronounced in a word, for example the M at the beginning of Megan. The K is pronounced the alphabet way, however, i.e. not in the way you would say "kite". It also can be used to ask someone to do something, as in "Pick up Tommy, mk?" Instead of "Can you pick up Tommy?"
Pick up Tommy, mk?
Let's go to school, mk?"
Dude you just met her.
Dude M.K. is different not like when other girls say their different.
Dude ask her to be your girl you idiot.

Used colloquially in British Columbia, to describe the action of selling out without good reason. The term is thought to originate from a metro vancouverite named Mark Kim, well known to his community as a martial artist and educated person. This potential origin is backed up by evidence of Mark Kim calling off his attendance to several events for poor excuses such as fatigue or lack of interest.

Person 1: Dude, I'm tired and I don't feel like going...
Person 2: Kyle! Don't MK it!
