Nicknames can end up being either one of the coolest things about you (imagine someone calling you ‘Wolf’ or ‘Ace’) or so embarrassing that you wish nobody ever ends up hearing them again. There’s a small problem, though: you can’t give yourself a nickname; others do it for you. And you can earn your nickname—whatever it might be—completely by accident, without even knowing that some random action will end up defining you for years, and sometimes even decades, to come.
