A physical act that involves running at your target, usually another person, then jumping and twisting in such a way that your ass lands as high up on their body as possible (preferrably the face). This act can be performed from a higher location, such as a bench or car, in order to get your ass as close to the target's face as possible. The only requirements to qualify as a Flying Buttress are that your feet leave the ground, and that your ass hits the target before any other part of your body. A knockdown is considered a bonus.
Everyone feared Tony's Flying Buttress' because he usually performed them without pants.
