The act of knocking a woman out during intercourse with a sharp blow to the head, positioning her belly-down at the top of a staircase, and then while sitting atop her back, riding her limp body down the stairs. This act is performed much in the same way a sled is ridden down a snow-covered hill. Steering is accomplished by bringing the arms up behind the back; pulling on the left arm turns the sleigh left, and vice-versa for pulling on the right. This act is almost guaranteed to be good fun for at least one person.
"Why is Mary's entire face in a cast?"
"Ohh, Ted gave her the old nantucket sleighride."
"....oh, what fun."
