I always say "minus $x$", but then again that's because in my native language (Spanish) that's how we say it.
In any case, $-x$ is the result of applying a unary operation to $x$. Hence it sounds strange to me to use the adjective "negative": surely "negative" is not describing an attribute of $x$ nor specifying it further, but actually changing it altogether!
