Is it Boundman or Bounceman? Luffy displayed Gear Four for the first time against Doflamingo and called it a specific form.  Via Funimation subs I thought this form was called Bounce Man.  The wiki calls it Boundman.

Is one of these two names offically correct? If Boundman is correct, what is this referring to?
I have not watched One Piece, but after reading the Gear Four Techniques wiki, both Boundman and Bounceman are appear correct - it is just a matter of how it is translated.

Boundman
Luffy's first Gear Fourth form is called Boundman (弾む男 (バウンドマン) Baundoman?, literal meaning &quot;Bounce Man&quot;; Viz and Funi subs: Bounce Man):

When plugging in 弾む男 (バウンドマン into Google's Japanese to English, it translates the text to

Bouncy man (Bound man)
