What does Aggressive DSD mean?

Aggressive DSD meaning in Urban Dictionary

a sexual position wherein the person is behind the girl and both tend to be completley horizontal. Just like typical doggystyle but both lovers are laying level, ergo "down" in DSD definition "doggystyle down". As soon as doggystyle is doggystyle down the man grabs each of the womans wrists along with his left-hand and also as much locks that you can together with right hand. Just achieving the place will not represent true intense DSD. Extreme neck cranking, wrist bending and butt pounding must be done.
