Headset procedures assume that both parties understand each other. If there is ever the slightest doubt, hand-signals are the safest method.
But even if there is a common language, the crap I don't want to hear is "The preflight inspections and all safety checks have been completed. The stairs have been removed. The doors and hatches are secured. The towbar is attached and the tug is ready. Blah, blah blah..." The one word "Ready" would suffice.
