The waterfall is when a female squats over a toilet and begins peeing, only to realize afterward that the seat cover was down the entire time. This female will probably have to change her pants and/or her shoes after accidentally pulling this move.
That dubb giving girl not only got the hot karl, but had a Waterfall in the bathroom and had to change her pants, socks, and Ked sneakers.
