Suppose you had to pick one word to describe yourself. Your first reaction, I assume, is that it is impossible. You are so many different things, in so many different contexts. No one word can capture more than a tiny slice.

Now suppose I ask you to think of people you know, and see how many of them you can describe in one word. Suddenly it gets a lot easier. He’s a jerk, she’s hot, he’s a loser, she’s a nerd, etc.
