A sexual position in which the male bends over and sticks his dick backwards between his legs and the girl backs up onto his dick while making beeping noises like a Mack Truck. Variations include the Wide Load (women in excess of 200 lbs.)
Guy: Yo my girlfriend pulled the Mack Truck yesterday. I nutted everywhere
Other Guy: Dude thats so ballin. Did you try the Alaskan pipeline after?
Guy: No I've been constipated for weeks so I didn't have any frozen shits laying around
