The well-known ship name for Ruby and Yang is Enabler... There are plenty of determined people. They're so determined that they're hoping and insisting that Ruby and Yang aren't actually related so people will stop calling it an incest ship. Sorry, but they're half-sisters, thus half-blood-related, so it is incest.

Anyway, the team attack thing was inspired by the dwarves' attacks in The Hobbit, apparently, but the team attack names were inspired by shipping names.
