I can't give you a definitive answer, but your question does remind me of a blond joke spin off. (I don't care for blond jokes and I don't want to highjack the thread, but I think this is relevant.)

A blonde's mating call: "I am so drunk!"

A brunette's mating call: "I said, I am so drunk! Isn't anyone listening?"

A red-head's mating call: "NEXT!"
