The act of giving someone an imaginary hand
job. This is done by shaking a a closed fist in the air, simulating a stroking action. This action is used for a wide variety of reasons, whether it is for raising morale, thanking someone, or congratulating someone. It is in no way wrong for one
man to give another a notional hand
job, because the it's notional, and not
real. Either sex can give either sex a notional hand job.
