Saving the next person who also didn’t know what turgid meant a Google search:

Turgid (adjective) - swollen and distended or congested - (of language or style) tediously pompous or bombastic

That sounds like it conveyed the meaning perfectly: they wanted to present an idea that struck you as smart, but which you didn't understand -- we're meant to see the show as Morty, not Rick. So we just get a Rick-ism that clearly has some structure to how the Ricks are organized (which the Ricks understand), but which doesn't immediately mean anything more to us. Rick and Morty isn't a science lecture -- we should expect narrative language, not scientific language.

It suggests that the Ricks are organized around some central, finite core of Rick-ness that we don't know about (notice that they have worse lives as they acquire letter variations on their curve numbers, eg TV personalities on the citadel). That's the point -- they don't want to get into a detail physics argument about it, but frame a (later revealed) structure among the Ricks.

I just don't think we should assume that structure is the shell of a normal distribution instead of something Fry-esque (ie, I'm-my-own-grandfather shit) -- we should leave them the room to insert whatever structure fits narrative-wise when we get to the point that makes sense in the story.
