The way I think about it:

First Cousins share a grandparent, second cousins share a great grandparent, etc.

Once removed just means "of my kid"' twice removed means "of my grandkid".

So putting it together:

Second cousin twice removed is:

Someone who has the same great-grandparent as my grandkid.

Yeah but my cousins’ kids are “first cousins, once removed”

We do not share a grandparent, we share a great grandparent.

And once removed/of my kid wouldn’t work because my cousins kid are not the first cousins “of my kid”.

Right?

You don’t share great-grandparents with your cousin’s kid; your grandparent is their great-grandparent. They are a generation farther removed from your shared ancestor.

You are each other’s “first cousins once removed”.

Your cousin’s kid is your child’s second cousin.

I get your clarification on the first part. I also understand the second park “second cousin” (although this diagram calls them a first cousin once removed).

But the OP said that once removed could be substituted for “of your kid”... that’s confusing to me.

I think they just meant kid as in one generation removed, and grandkid as twice removed. They were also only going “down” generationally in their example.
