What The Hell's The Point Of Fight Clubs?

So today someone on my facebook posted a video of a fight. What it seemed like was just them fighting for the heck of it and I'm wondering, what's the point? Like I'd get if there were bets being placed but it was freshmen. And I get it proves muscle and gives you a reputation, but like without a reason? The fight was amateur though, I mean there was only one punch, that flowed into being a headlock, the became to faggots wrestling on the ground. In the end it looked like they were cuddling after sex. I just can't fathom the inspiration behind it. Fight clubs are different, but they're the closest thing I could think of to compare what happened in the video today. I mean I'd fight, and I could win, but if I had a reason. I'd just get in close and pound on the bitch til' they pass out and someone has to pick me up off of them. If I get in a headlock it's worse though because I can easily elbow them and hit them with my head, which as far as I know hurts a lot. But it was only the second one I've seen posted to facebook, and I have to say it was just retarded. They follow the kid for 30 seconds, then lose him, then when they find him he turns around and puts his fists up wrong. Then I saw him go off and punch, but it failed. I mean people are just dumbfucks that think they can fight sometimes. When they go up against someone that actually practices they're gonna get their asses handed to them.
