in the indigenious process of "eating a girl out" you may be stained by blood from her menstrual cycle in the shape of "wings," therefore you have blood on the sides of your mouth. Thus the "red wings" are born.

for the sake of privacy we will call my friend... Bob. Bob thought it would be a good idea to do some k-pins, after a long night of drinking, fraternizing, and k-pins... my friend BOB started to do the "K-pin shuffle" and in his condition thought it was a good idea to go down on a girl... who was on her period........ twice... blah blah blah... long story short... dont wear a white t-shirt in the process... or try talking to family members
