to catch your female partner's cum in your mouth when she squirts and then stream or spit it back onto her or into her mouth
Have you ever squirted in a man's face and then watched him while he is waterfalling onto your tits? I have.

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.

A waterfall is when a little bit of smoke is still in your mouth and is forced out and is then inhaled through the nose and it looks like a little updide down waterfall. It's not really going to get you more high, but its a cool little smoke trick. Don't fuck up or you'll just end up with a smaller hit.
Damn....i fucked up on that waterfall and just lost all that smoke.
