Haven't heard of it, curious the reasoning behind the number though. Pretty sure most girls would make comments saying they're more of a man tho, I mean i'm 1/16th black and joke about what part is 1/16th.
My girlfriend and her family, and friends are all racist. It's weird, never really met a legit racist (going by real definition, not sjw definition) then BAM everyone i meet is racist suddenly. WTF. BUT, they're still people, everyone's got flaws. I do say i'm 1/16th black tho to piss em off. To which one says "ohhhh nooooo, well..... at least you're not jewish". So now i say im jewish too, can easily pass as one lol.
