Surrender

Before the last blow can fall, and before anybody can help you, you slip your hands behind your head in the tournament gesture for surrender.

The bell rings immediately, and Piet gets off of you. You may have saved yourself from a royal ass-kicking, but surrendering has its own consequences. You take off your own jockstrap and toss it to the referee, who shakes his head in disgust. Surrender is not looked upon favorably in this tournament.

You continue the ritual of surrender by leaning back on your knees and exposing your body in full. When that's done, you finally finish by getting down on all fours in front of Piet... And groveling in front of everybody. You bow down repeatedly, kissing his feet and prostrating yourself.

Piet accepts your surrender, and the referee tosses him a thin rope. He uses that rope to tie your wrists behind your back, and grabs you by the arm. Since you surrendered, he gets to lead you back to the lockers. Bound, naked, and defeated. The loud boo-ing of the crowd follows you all the way there.
