did the person telling you hold his wrist about face height and shake it up and down like in the coffee bean commercial?
if so it might mean something else
or
it means you either break the wrists too early going back or more likely going through. Do you thin a lot especially with short chips?
I assume they were talking about your chipping or putting. It means you are getting too much wrist action into the stroke. If you are having issues I suggest you search for V-Easy and ask Bob Mac to sell you one
