The 3D is the finishing move of the Dudley Boyz, a WWF (and formerly ECW) tag team. It is one of the few two-man finishers, and was invented by Dean Malenko.

To execute the 3D, a standing, groggy victim is lifted up and at an angle by one man (usually D-Von Dudley), and then caught by the head in a headlock by a second man (usually Bubba Ray Dudley). Imagine a Stone Cold Stunner, except with a hoist into the air.

The nice thing about this maneuver is that it is very useful for putting people through tables, a signature spot for the Dudleyz.
