Mak kau hijau 

"Mak kau hijau" is a Malay phrase which literally translates in English "Your mother is green".

This phrase origin came from a video that went viral in Malaysia about 2 kids was insulting each other. One of the kid spontaneously said "Mak kau hijau" maybe because out of words after being insulted and angry at same time. The reason it went viral because that phrase has no meaning of insult at all and it is funny when he said that. That is why netizens of Malaysian keep spamming each other with this phrase at that time more just like to joke with each other.

The phrase itself has no insult meaning but when foreigners comment something bad about Malaysia, they will get floods of reply "Mak kau hijau".
Hey bodoh, mak kau hijau!
Hey stupid, your mom is green!

Back when I lived in upstate new york 

A meaningless, unimpressive, self-serving introduction. An indicator that the story about to be shared will be pointless and dumb.
Back when I lived in upstate new york, I also had to park on the street - on two occasions, we got enough snow, mixed with just the right plowing, that my car was lifted off the ground from so much snow being jammed underneath it.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
