A play on the terms "backstabbing" and "twist". Figuratively, backstabbing in an office would refer to betrayal, e.g., by passing someone over for a promotion. But here, the backstabbing in the office is literal. Furthermore, the "twist" is indeed a figurative twist, i.e., an unexpected turn of events. But, it's also a literal twist added to the backstabbing: instead of stabbing with knives, employees are backstabbed with literally twistable "keys" that are usually used to wind up, e.g., toys.
