It's simple you write something down and it could be anything just that you end the sentence with "My hill"
I start with saying: "I walk up the hill and take it. My hill"
Which makes me the current king. All you have to do is post something similar, for example:
"I walk up, push you into a ditch, teabag your body and then claim the hill. My Hill"
If everything is clear then let us begin!
I walk up the hill and take it. My hill
