I used it to connect a generator to the wall and give me some temporary power in my house when I was renovating. It's only dangerous if you are stupid.

If I ever buy one of these, I'd only ever use it to encase in resin and put on a shelf as a comedic ornament.

I worked at an electrical supply store foe a while. The amount of people trying to make these is really way too damn high. At least once a week.

I heard there was a secret cord.
you plug it in to meet the lord.
But you don't really care for safety, do ya?
It goes like this, you plug it in,
And in a flash, the lights go dim,
The power's gone,
and now it’s running through ya.

Fine, I'll just use a couple of those with an ethernet coupler.

On the one hand, there are legitimate uses for double ended male cords. On the other, absolutely none of those legit uses invovle christmas lights

as someone who has strung a ton of lights the wrong way around on more than one occasion... I can understand the desire for some magic solution that doesnt require undoing and redoing your work..

but fuck, You don't mess around with electricity.

People also make these stupid suicide cables to plug generators into houses during disasters, often backfeeding power into the lines that may be down and can cause serious injury to workers trying to restore power.

... but you don't really care for logic do ya?

They tried calling it a doom cord, but heavy metal band started having electrical problems.
