In the description of that video, WWE has already renamed the group of Charlotte, Becky Lynch, and Paige. The girls previously went by “Submission Sorority” stable, but as noted, that is a porn reference.
WWE is now calling the group “PCB” or “PaigeCharlotteBecky.”
PCB’s Charlotte & Becky Lynch clash with Team B.A.D.’s Naomi & Sasha Banks.
Also, WWE.com has a poll mentioning the group with that new name so it appears that the group will now be called that.
It should be noted that during SmackDown, Charlotte made her entrance and during it, the graphic with her name had “Submission Sorority” under it. WWE could have changed the name after SmackDown was sent out on Wednesday to their TV partners and couldn’t’ edit the new name of the group into the SmackDown broadcast.
