A sexual position similar to the rear admiral. A man enters a woman from behind, with the woman wrapping her legs around the back of the man. The man then positions the woman onto a rolling, wooden cart and proceeds to roll her around the room, a la a covered wagon. This can get extra kinky if the man dons an old cowboy hat and calls the woman a dirty ox.
"Jasper, remember when you pulled The Pioneer on me? That really took me back to the Oregon Trail days!"
