The Flying D

When you use your fully erect penis to hit someone, i.e. your friend or lover, in the face. You must run across the room adjacent of the target, yelling their name; at the mid way point of the room, to gain their attention, then aiming for the nose of said person after jumping in the air, bringing your erect penis down like a drop kick.
If done correctly, their nose should be bleeding.
