It will be underwear soon after they apply the strightjacket.
You'd be called superman if you did.
It's still called underwear . .no matter where you choose to wear it. If you wore your gloves on your feet, they'd still be gloves. Misuse of something doesn't change its name .. lol
You can call it whatever you like .. it's your undies! lol
in that case you're a superhero.
