Call him Master and act submissive

As you look up to the wild man, the power dynamic on this island becomes clear to you. There is he, a hunk of a man that could probably break you in half, and you, naked and afraid. You realize that he is your best ticket to survival in this dreaded place. So you need to get him to like you.

Slowly but surely you get up on your knees. You place your hands on the ground. Now on all fours, you look up at the brawny mountain of a man. Trying to sound submissive, you let out a sultry "are you my master?". You look at him with begging eyes. Does he even understand your language? Was he stranded so long on this island that he forgot proper words? Whatever it is, he look at you with a puzzling look at his face. Darn, you think, he is not getting it.

A thought crosses your mind, what can you do to make it clear to him that you are submitting to him? What gesture would transcend the language barrier between the two of you?
