Matt Gauthier demonstrates how to do the Alien Birth Ritual. This move has become legend because it has an awesome name and because very few people can do it. In fact, very few people can even describe it.
It starts with a birth. However, you pivot on the “birthing leg” to extend the against the spin pull. Then you set it up and immediately pull a juice.
It took Matt two tries to do it for the video…hence the cut.
Juice: With Clock spin, set the disc on the left side of your body. Now, reach behind your legs/under your left leg with your left hand and pull the disc against the spin so it traverses between your legs.
