You find yourself wanting to fornicate doggy-style, however, there are no chairs and/or stationary objects nearby for your partner to put his/her arms on--so essentially he/she is standing up, bent over, looking at their feet whilst receiving a meat-bat. While doing this, you steer your partner (unknowingly) little-by-little until their head hits a wall (if you're a real sport, you'll give it a little UMPH as their head hits the wall)..you then yell something to the effect of "AHOY MATEY, YEE HAS HIT LAND!!"
