Just because you opened up this post, I'm going to say the chest bump is the greatest celebration known to man. It should be mandated to do not just in sports, but in everyday life. If you see someone picking up trash, chest bump them. If you're at work and your boss gives you a promotion, chest bump them. If your dog finally learned how to take a sh!t in the backyard instead of your living room, find the nearest person, and chest bump them.
