Hehe, it does kinda sound like something you’d see in one of those teen horror movies. Maybe a weapon for a new Dead by Daylight killer.
At a former MK forum I was on, someone came up with erh… “creative” new fatalities which all included mutilating genitals in all sort of bizarre ways. And said person kept suggesting it becoming a thing in the games, to the point of how obvious it was that it was indeed a fetish of his.
I’m not squeemish at all, but even I was kinda “WTF dude?!” about it. XD
