Xian, or X-ian, or its permutations, which, apparently in some circles, means "Christian".
I get it. But I don't like it.
Because when I see "Xian", I get all excited and ****, thinking they're going to talk about some ancient Chinese dynasty. And then X-ian makes it look all alien, so we'll be talking about invaders from deep space.
But then they rant about Jesus, and I lose interest, 'cause that ****'s boring.
