IDK if it was a normal meme/fad anywhere else but my high school had a brief spell where guys would try to rapid-fire distract girls with questions and stuff, then quickly ask them what color their nipples were in order to find out.
Were we all smarter, we would have known already, but it was titillating and hornt and we were all fourteen, so the prank continued until it was condemned and penalized by our aged spinster principal.
It's a tiny bit sad how women can conjure up such mental wounds from the simplest things, but they really did have their own little caste system arise instantly. Sure, it's a matter of taste, but pink was the nobles' choice.
It's weird to think about it today, it would be a full on local news report hysteria. Back then you'd only really ask girls you knew/liked/flirted with already. Not sure it would be possible in the diverse schools of today, 10 years later
