The Charlie Brown buck is a painful sex move. It is done when the man is getting sick and tired of the old lady and just wants to end it as quick as possible, but without words being exchanged. The move is performed when the man is having sex with his girlfriend in the standing doggy style position. While thrusting in and out the man will scream the words "Charlie Brown" then immediately thrust his shaft into the girls brown eye. This will drop her to the ground, and then the man will finish by doing the snoopy dance around her while she is crying.
