Lumberjack Smack 

A highly technical sexual move pioneered by the Lumberjacks of Tennessee. A heavily built, extraordinarily strong Lumberjack takes hold of his testicle sack and swings it in a circular motion as fast as possible. Then, when maximum velocity is reached, the Lumberjack screams a Lumberjack scream "Timber!" and smacks the clitorial region of his female partner with his fast moving testicles. If done properly, the female partner's cry can be heard from the Mississippi River.

After a long day of sweating and being strong, Larry the Lumberjack just wanted to go back to his log cabin and give his bitch the Lumberjack Smack.
