This is unhelpful quibbling over the semantics of one word. You know what I meant. Everyone knows what I meant. I even explained in more detail what I meant. You're also wrong about the word, but I'm not going to bother arguing that here.
Please refrain from writing "this meat smells funny" comments on HN. You could go around commenting on typos too, which happen all the time, but that's not at all helpful.
