A simple electrical cord that has prongs on both ends. Thus, if you plug one end in to a live outlet, the exposed prongs are energized and dangerous.

Such a device is actually useful, for example, to "inject" power into a dead circuit from a generator. However, due to the inherent safety issues, you generally can't find them for purchase, nor would a licensed electrician ever provide you with one. Thus, do-it-yourself handymen are left to splice together their own version of this device (probably making them unsafer).
When the hurricane hit and the power went out, I fired up the generator and jacked it in to the outlet in my garage with a suicide cable; at least I was able to run a few lights and my refrigerator.

Get the suicide cable mug.
A power cable that is cut, stripped, and crimped with alligator clips in a manor that will allow the user to clamp the clips on his or her body and plug the cable into a wall. This will result in an excruciating electrocution or even death.
Pierre was feeling a bit down so he offed himself with a suicide cable clamped to his balls and tongue.
