My partner and I have been calling them "fun boxes", as in, "Hey, I just started to poop but I forgot to bring my fun box, can you grab it for me?".
I started it maybe a couple of years ago. Was aiming to give myself a verbal reminder of their skinner box nature every time I mentioned them while keeping a fig leaf veneer of comfortability so I didn't have to explain if someone else overheard. Maybe didn't go hard enough with it; about a year ago it came up that my partner had been taking the name at face value and didn't ascribe anything sinister to it.
I'm not.
