ELI5: Why do professional fighters "hug"? Is that any kind of defense? Does that have something to do with any rule?

I think you're referring to the clinch.  In most forms of karate, the clinch is a position from which you perform a lot of throws or strikes (such as knees to the head, or elbows to the head).  In boxing, it is a defensive move to make sure that you do not get an uppercut or hook to the face.
