Flying Fun is a sex position designed for maximum effect. The giver is standing, with his arms stretched back holding the ankles of the receiver. The receiver is facing the ground and has their hands on the thighs of the giver.
This position is only for the experienced. One slip and the receiver falls flat on the face. Not very fun.

There is a variation to it called flying fun variation, which is a bit easier for those who are not quite as experienced.
