There is a tweet going around which women find hilarious and apparently men don't understand. I have to admit, I am stumped. Even after Googling I have not found an explanation, or at least I don't get the explanation either 
Is it a hair joke?
Seeing as we have such female contingent in GD I thought I would ask here, any ideas?
