Given that it's not inside anything right now, this isn't exactly an endoskeleton. Right now it's just an extremely skinny clockwork robot. But it's brimming with endoskeletonic potential. Just don't roll down the street smokin' it and sippin' on gin-and-juice-skeleton.
The description refers to the chorus from the Snoop Dogg rap song Gin and Juice, from his 1993 album Doggystyle: "Rollin' down the street, smokin' Indo, sippin' on gin and juice" (Which phonetically sounds like "Smokin' Endo, sippin on gin and juice").
The "gin and juice" reference is doubly clever and doubly useful, as it gives a hint towards what you could actually "cook" the endoskeleton with, as the endoskeleton is (unlikely as it seems) a cooking ingredient.
An endoskeleton is an internal support structure of an animal, as opposed to an exoskeleton.
