I believe that the syntax of the call Bounce is 'active-dancers Bounce (The) designated-dancers'.

'Everybody Bounce' means everybody is active and all do the call 'Bounce'. Hence this means to 'Bounce Nobody'. Personally, I believe that the callers should always specify the designated dancers (e.g., Bounce Everybody or Bounce Nobody). I do not like it when callers use 'Bounce' to mean 'Bounce Nobody'. They certainly don't do this with similar calls such as 'Patch' or 'Tap'. Have you ever heard a caller just say 'Patch' and expect everyone to do a 'Patch Nobody'???. I don't like it. I also think that callers should be required to give the direction for calls such as Spin Tag The Deucey.

Ceder Chest Definition of Bounce anyone
