A young brave was watching how the Big Chief came out of the tent from where a baby could be heard crying for a moment, he looked about and then disappeared back in.
When he came out again, the young brave ran up to him and asked him: Big Chief, how do you decide on how to name the newborn babies? What gives? Go on, tell me!"
"Well" says the Big Chief, it is like this: "I come out of the maternity tent and look around. And take my clue from the thing I see first. Just now for example, I saw a lovely silvery moon shining from beyond the silver clouds on the lake over there. So I just called the little newborn, Shining Moon From Silver Cloud Over Lake. Anyway, what's it to you, Two Dogs Fucking?"
A normal phrase.
