No siblings consider themselves as “cousins” to any degree and no English speaker uses these terms. You’re right, of course, about the terminology that we commonly do and don’t use. The notions like “zeroth cousins” and “zeroth cousins once removed” are descriptive terms that describe how these relations stand with respect to one another, as in the “consanguinity” chart that @Dewey_Finn posted. The entire second column in that chart are the “zeroth cousins”, and the entire row beginning with “Person” are the “zero times removed”. The recent thread I mentioned, and the particular post (by @Chronos), is this: > [@What do you call this familial relationship?](https://boards.straightdope.com/t/what-do-you-call-this-familial-relationship/961655/18): > > All brothers are, in fact, cousins. Zeroth cousins, if you want to be more precise about it. And there’s also such a thing as double cousins, where a pair of siblings from one family marry respectively a pair of siblings from another family, and then have kids. Those kids definitely aren’t siblings, but still have all four grandparents in common. Searching this Board for the phrase “zeroth cousin” finds about 15 prior mentions of the phrase. --- _[View the full topic](https://boards.straightdope.com/t/your-cousins-son/962592)._
