You can call it Bitcoin Cash or Bitcoin BCH. It's not a big deal. People will know what you are talking about.

But there's a point to be made here, that if the old Bitcoin recourses such as the Bitcoin.org, the old Wiki, BitcoinTalk and r/Bitcoin had not been manipulated and if the pre-scheduled scaling roadmap as per the Bitcoin design had been continued without introducing SegWit, the fork would never have taken place.

Then there was the swamping of Twitter and Youtube with automated "bcash" spam etc, but that's a different chapter.
