The Big Kahuna; the main event; the money shot. If you want to make it to the top of the gesture game then read on, friends.
Ignoring the two bumbling chumps you see above you, instead enter in for a handshake and then, at the last moment, clench your fist, hone your gaze and demand a fist bump from your trembling foe... or your boss.
Either he'll wrap his hand over your fist like a flummoxed octopus (revel in his squirm) or he'll be inexorably drawn into the cold vortex of your fist bump; your finger bones locking as his pleading eyes search for answers and mercy.
Of which there will be none!
Recommended accompanying phrase: "Send the fleet to the far side of Endor. There it will stay until called for."
