Schools taught us a lot of things. In fact, without schools, we would all be illiterate idiots roaming the face of the earth. But schools also taught us a lot of unnecessary stuff. I mean, if you did not become a science or maths student after school, trigonometry has literally zero use for you.

But we are not here to criticise schools. Or trigonometry, for that matter. We are here to talk about certain words, a lot of them, mind you, that we haven't used since we passed out.

See, when was the last time, you used them?
