Eating Crow is a third world scarecrow. First, place the disc upside down in your mouth. Bite down on it so the rim is just behind your canine teeth. Bend forward and then toss your head back, throwing the disc up with a third world spin. As it spins count the rotations to get the timing. Now, catch a scarecrow. Time the catch with the disc rotation so the it is flat when your hand arrives.
Once you perfect this trick, then next question, what trick leads up to having the disc in your mouth. If you have an idea, let me know in the comments.
