I never knew there was a Handkerchief code until last night. I feel like a dumbass. There are intricate color codings of these Handkerchiefs. Warning, very graphic, expletive laced color code charts. God help us!

I heard of that before, and IIRC, handkerchiefs figured in some Podesta the Molesta emails.
It’s what started “pizzagate”
This reference to such in Podesta e-mails made no sense otherwise: https://wikileaks.org/podesta-emails/emailid/55433
Sheesh! Even a white handkerchief sends a perverse message to these folks (you're going to have to look for yourself if you really want to know).
