lol does it count as "slang"??
I'm pretty sure i just heard about this thing a few days, but I saw on some completely unrelated youtube video today the guy described it and apparently its just from some random video on the internet where someone has their arms out as if they are weighing two options and they say "6, 7" as if those are the two options. Not sure if the video was funny or something, like why it became a meme, but yeah, it's literally a meaningless thing. It's not some sort of slang or has any sort of meaning, just meaningless reference to some random video. Basically the dumbest yet example of a meme.
