That's how they express affection.
The best man and the groom often share a strong bond, often rooted in a long-standing friendship or family connection. They symbolize a close brotherhood with a unique camaraderie. However, there are exceptions, such as the unusual situation depicted here.

The cause of this unexpected brawl remains a mystery, leaving us to wonder if it was a personal dispute or an ill-conceived attempt to recreate a scene from a movie like "Jackass."
