The sexual position in which a female human being lies on her back (on a bed, sofa, moose, tent, bubble wrap, trampoline, etc.) and a male human being jumps into the air, does a full 360, and slams his balls into her face.
As Ryans mom lies on her bed, Tyler leaps into the air and slams a Helicopter Ball Drop into her face. She screams with plessure!
