When performing a Golden Handshake (definition on this site), one pretends to accidentally overshoot the forearms, faking apologies the whole time, but continuing to soak the would-be business partner's torso and legs in piss until one's bladder is completely emptied (excusing it all with "once I start I can't stop--it burns"). This technique is often used as a subtle form of mockery of the would-be business deal, or a way to express doubts of the profitability of the alliance.
Eager to seal the deal, Henry agreed to the Golden Handshake but was somewhat hurt when John surprised him with the Golden Overshot.
