As told in Chapter Two, what does “L” mean to Shawn and Will? What is the game they used to play on the elevator?

“L” meant “Loser” to Shawn and Will. As kids, Shawn and Will would play the game on elevators to get on an elevator and wait for someone to get onto the elevator and press the “L” button. Shawn and Will would laugh because this meant that the other person was a “Loser.”
