The osis movement is one of the more difficult movements to wrap your head around. In this video Matt demonstrates the most basic osis behind the back (BTB) catch. So, what is an osis? It’s anytime your body rotation is moving in the same direction as the disc. As Matt demonstrates, a BTB is either static or you twist towards the disc to make the catch. For the osis, you must rotate away from the disc as you catch it. This makes for a very small catch window as your hand can only stay in the right place to catch for so long…your rotation will pull your hand away. It’s really all about timing. Also, as Matt points out, osis is a blind catch in a way. You have to watch for as long as you can over the opposite shoulder and then, at the last second, snap your head around to make the catch. Of course, unlike other blind catches, with the osis it’s ok to turn and face the disc as you catch it, watching in into your hand.
One cool thing about osis is it can be added to most catches. A flamingo can become a flamgosis, gitis becomes gitosis, chair becomes chosis, and bad attitude can be a bad attitosis. All these catches are extremely difficult and can be quite beautiful to watch because they require precision timing and body mechanics. What’s your favorite version of the osis?
By the way, I’ve heard Chipper “Bro” Bell call it a reverse pull when you do an osis pull.
