Mud Diving
We guess that it is safe to assume this is a competition of some kind. Look at the adoration and jubilation of the crowd, egging her on to do something that almost anyone would not. If it’s a game, then we are certain it is popular.
It is about as jovial as a drinking game, too, with people cheering as if this woman is chugging the keg. Kudos to the photographer for the perfectly timed photo. Though we would have loved to see the satisfying splat once she reaches the mud!
