Ah, the Etherkiller, +5 Utility Cord of Smiting.
... is there any use for that thing other than arson? 'Cause I'm just not seeing a benign function for a double-ended plug and it's just too clumsy to be for torture or kink.
-- Steve's brain is insufficiently caffeinated to process this concept. (A)bort (R)retry (F)ail?
Also useful for stealing electricity on the sly.
For when you've put up your Christmas lights and got them all strung just the way you want them and then realize, crap, the end of the strand next to the wall socket doesn't have prongs, and the end with prongs is nowhere near the wall socket.

Before we had "the cloud", there would occasionally be a single computer that was very important and could not be turned off. Perhaps it was processing a hundred queries per second and downtime would cost millions of dollars per minute, or perhaps the filesystem had not been unmounted in forever and the next fsck would be unskippable and take a year and somebody who had long-since left had changed the password that keeps you from changing the boot options, or perhaps you didn't want to interrupt the 100 GB file transfer running on the 1200baud modem.
Unfortunately, whoever had first bought the machine had neglected to put it on an uninterruptible power supply with generator backup, and a long series of lazy and/or skittish admins had never bothered or dared to bite the bullet; and today someone brought to your attention that the power company is doing "maintenance" tonight---the "turning it off for a few hours" kind of maintenance.
There's a generator and UPS ready to go. Too bad that in order to move the power strip over to them, you need to unplug it. ...or do you?

Feeding a large stage dimmer power distribution from the "wrong" end. Times to do this are when a) you want to program lights at an outdoor concert in the middle of the night (since it's dark, duh) and b) the generator is offline and the shore power isn't connected c) You really need to test the dimmers (and not just fixed power for say moving lights) d) the generator guys are asleep and really pissed if you wake them up.
The dimmer guy came over to us electricians and asked for a male-male 63A three-phase cable. He explained the situation. We understood, told him he was crazy and showed him where our connectors + cables were and turned our backs.
Large concerts are usually powered off generators since the local feed can't handle the amount of power, and they usually have a 63A three-phase "shore power' connected, if nothing as a "clock reference", so you can pull a small (<40kW) load without the generator having to run.

haha, I was thinking this was some sort of homophobic metaphor.
... No, I think it's more just the kind of sign that the dudes at the "custom power cords" station might have to put up.
I may or may not have considered constructing one of those to pipe power from our portable generator into the house circuitry without the expense of incorporating the proper routing through a cutover switch and the breaker panel..
Or, in other words: If you know enough about what you're doing to know when this is the appropriate solution to your problem, then you don't need our help to make one. If you can't make one without help, then you shouldn't have one; you might hurt someone besides yourself, and that wouldn't be right.
And if you know just enough to make one or use one poorly, you will be identified on the evening news.

I'm sorry, I don't understand
Are you serious? Because we could explain, but I don't know if you're actually asking or not.
