Russian Dolls

I've been using the phrase Russian Dolling for some time now to describe at least 3 pokémon (or misc. hungry things) where a pred eats a prey and then get eaten themselves by another pred.
Or if a pred eats two others, then one of the two eats the other whilst inside the first's stomach (So it's one thing inside another, inside another, etc.)

I pretty sure this type of vore exists, and it's probably been named already.

I want to know if it has?
Was I close?
And if it hasn't, could Russian Dolls ever become the term for it?

I've seen it before, but never heard a term for it. That's a really good one actually.

I don't think it has a term...though I agree with russian dolling becoming the term.

isn't that double vore?

Yeah, I also have been refering to it as double, triple, ect. Vore.

I think that the generally used term is Turducken- A turducken is a dish consisting of a partially de-boned turkey stuffed with a de-boned duck, which itself is stuffed with a small de-boned chicken. The word turducken is a portmanteau of turkey, duck, and chicken or hen.

At least, That's what I've heard, mostly. I think turduckening someone just sounds a lot dirtier than russian dolling them, and turducken also has to do with food, anyways. At least, that's what I use.
