In the context of Social Play, typically while sitting or kneeling, or when Mud-Wallowing or Bathing in deep water, raising the head vertically and then tossing the trunk high in the air and allowing it to flop down over and onto the head.
As Big Mama exists a mud wallow she raises her trunk and flops it on her head. This is not a particularly good example of this behavior, as although it is often associated with mud-wallowing, it is more often in a clear association with play - for example, in a mud-wallow or in the water. (Maasai Mara, Kenya)
