Stumped for tag name: helix/spiral/drill/braid ears, maybe?

Caught something in post #625607 that might be tag worthy, but as usual I'm getting stumped on names. Look at Reisen's bunny ears in the lower right panel. They are twirled together into a double helix shape. I'd swear I've seen this elsewhere in the past couple of months, but no quick searches reveal more posts along that line.

So, helix ears, spiral ears, drill ears, braided ears, what?

Oh, just to complicate matters, a similar concept comes up in the context of tails in post #864964.

For tails, there is intertwined_tails. The tails involved can belong to one or multiple characters.

I believe that the *_ears concept you describe needs more examples on danbooru before it gets worth tagging.
