A move performed during sex that has the woman on bottom, with her ass pointing up (achieved thru laying on her shoulders on the floor, with her back against the couch for support). The man positions himself so that he can aim his wang downward and entering her, either in the ass or the vagina. The thrusting motion looks like a oil derick pumping for oil.
Seeing the oil fields as we traveled cross country reminded me to give her the Alabama Oil Pump when we stopped.
