This is actually _exactly_ how language works, and that's precisely what's under discussion here: whether the term patent troll is accurate.

There's a different discussion to be had (which rayiner is also alluding to in his comment) about whether this definition has negative side-effects (like being too broad), but being clear on the terms being used in a discussion is important.
