Anton Volchenkov
A sexual maneuver performed when a woman is giving a guy head on her knees. When you you are about to bust you pull out and cum on her on a random place. The woman is on her knees (just like when you would block a shot) and just like a shot block, the shot doesn't always hit you where you think it will.
Jessica was severely pissed off. Shawn gave her an Anton Volchenkov that got her in the eye causing temporary blindness.
