Yeah.

Although I really truly do love mister Zhou's Baji vids I don't recognize his "jingangdabashi".

What it usually refers to is not a form at all but a set of 8 "trademark" Baji attacks. They are only "form" in the sense that the 5 fists of Xingyi are forms. Just a single attacking combo that is drilled repeatedly. There are 8 of them and that's what the name means:

jin gang: "divine warrior"
da: great/big
ba: 8
shi: moves/stances
