What is Backman?
1.
A slang term originating from rural Ontario, Canada, a backman is a particularly vile promiscuous girl. It comes from the fact that a backman is said to spend most of her time on her back, and also has the sexual appetite one would usually attribute to a man. Back+man= backman.
"I feel like such a backman, I've had five cocks inside me and not one of them was my boyfriend."
