An extremely difficult sex position involving a male, usually named Zach, and a female, usually very sexy and busty. The female lays down on her back with her knees bent and the male backs up a bit, then gets a running start and dives onto the woman, who then extends her knees, launching him into the air. Whilst in the air, if he has enough momentum, he can do a somersault, but he must land facing down. In landing, he and the female have sexual relations.
"He came in so fast, I thought he did a flying Zach!"
teenager: "I flying Zached your mom!"
Fellow teenager: "Your name's not even Zach!"
