Running the gauntlet is a game that some people play, but it's not a very nice game. Imagine you and your friends standing in two lines facing each other. You have to run through that line while your friends hit you with things like sticks, belts, or even their hands. It's like trying to run through a bunch of obstacles that are hitting you!
Sometimes, the people at the end of the line might also have buckets of water or mud to throw on you! So you have to run as fast as you can and try not to get hit or get wet. It's not very fun and can be very painful.
But it's important to remember that this is not a nice game and nobody should ever be made to feel like they have to play it. It's not good to hurt other people, and it's important to be kind and treat others the way you would want to be treated.
