Walkover backward/Backward walkover
The walkover backward also provides the option to do so with regular hand placement or alternate hand placement, like the walkover forward, though it doesn’t get a fancy name like the Tinsica. It’s just an alternate technique.
You’ll actually see backward walkovers fairly frequently on beam these days, but shhhhhh it’s a secret because we’re all pretending they’re back handsprings and are therefore eligible for series bonus. It’s one of those lies we’ve all agreed to give into, like “honesty is the best policy” or “beauty is on the inside.”
