low sac 

At around age 50 when mans testicles begin to sucumb to gravity, and are closer to his knees than his belly button.

Mike put his foot up on the bench after showering in the gym and unbeknownst to him his testicles swang out from below his towel and nearly slapped Tom in the face.

"Damn", Tom thought, "that nigga sure has got a low sac."

Low Sack 

1.An attractive looking car that might occasionally turn you on.

2.An offencive move where someone tries grabbing the testicles and ripping them out with their bare hands.

1. That soccer player almost low sacked the goalie when the game was over.
2. That low sack really wanted me to rub my hands on the engine.
