look up any word, like blumpkin:
The human sexual activity that is analogous to the coital actions of ducks in which the male mounts the female in a very domineering manner. He grasps her neck with his bill and submerges it beneath the water. This would be analogous to a man forcefully shoving a women's head or neck into the supporting surface while fucking her from behind.
Me: "dude, last night I was fucking this hoe from behind and grabbed her hair and stuffed her fucking head into the bed"

friend: "you duck fucked her?"

Me: "fo sho"
