Actually, they do exist; that's kind of the problem.

Here's a short extension cord version of one

The explanation of why they're a bad idea is valid though. Usually the kinds of people who know just enough to want this type of plug are also the type of people I wouldn't trust with one.

Edit: I'll go ahead and explain why people want plugs like this. These can be used to backfeed power from a generator into a house, letting you used different outlets/lights in the house. A knowledgeable person can actually use something like this safely, but most people who would use something like this don't know enough to do it correctly. The dangers about doing this are:

• You can easily shock yourself off of the exposed pins of the cord. You can avoid getting shocked by waiting to plug into the generator until the other end is connected first.
• You can backfeed power onto the electrical grid. The power going backwards through the transformers will step up the voltage to thousands of volts, and could seriously injure or kill the linemen who are trying to fix the outage. This is avoided by making sure you've opened either the house's main disconnect breaker or the breaker for the individual circuit you're plugging into.

There are some safer ways to setup this type of generator use, there are special generator power cords/outlets that won't have exposed energized prongs if plugged into a generator. There are also transfer switches or breaker interlock kits designed to prevent someone from being able to backfeed power by requiring them to disconnect commercial power before the generator can be fed into the house's distribution panel.

It cracks me up that they'll sell chainsaws to anyone.

They should put what they are called in the electrical world to help drive home the point. “Suicide cords”

It’s also a good thing dildos aren’t made of
metal and connected to voltage.

But... They do exist. They're just incredibly stupid and dangerous.

Was at a Christmas party last night and a guy dropped a 2 foot long double ended dildo on the table.

Male to Male adapters exist, but electrically questionable.

I hate that we live in a world where this is a popular enough question that a sign had to be made about it.

The fuck is wrong with people? Just rehang the lights! It takes less time and effort than getting in the car and going to Ace to ask for a deathdapter!

The electrical ones don't exist because it would mean you have exposed metal that is carrying current when a human touches it. However, for some odd reason you can buy it for control panels.

YOU CANT HIDE THE TRUTH

I have had this conversation multiple times, about multiple cable types, while in electronics sales.

I don’t understand this.

Do your Christmas light end with a female electrical socket?

What even is this? I never saw one in my life, so the sign must be telling the truth.

Ace Hardware has Dremels, solder, epoxy, and 600 grit sandpaper, and if you stare at this sign for no less than 40 seconds an employee will saunter up and you can ask them where to find all that stuff.

Now I really want one.

Pretty sad that it needs to be explained why these are generally a terrible idea

I'm sure you can find one on AliExpress.

I think thou dost protest too much. Perhaps not so much ace as you claim.
