Is it possible to hate the taste of water?

I've heard people say they hate water because it's tasteless, but surely if it's tasteless, you can't hate it because if you hate it, you mean the taste (which is non-existent, apparently.) Some people hate it because of the aftertaste. You always have water in your mouth, so you're used to it and some people say it tastes vile... Water's in so much that we eat and drink so how can one hate it? I think it's impossible to hate the taste of water. I might be wrong but I can't see why anyone would hate it..
