The Sack That Smiles Back

When the folds (Wrinkles) in a scrotum resembles that of a smiling face. Eyes and Mouth are required, nose is preferred, but not required. THE SACK MUST BE HAPPY!!! Must be declared by a spectator, not the one whom the sack belongs to!

If the "FACE" is hairy, 'Ball Bunyan That Smiles Back' may be decalred!

Donny: Dude, George, I think I got The Sack That Smiles Back, but I'm not sure... Help me out

George: O, definitely dude!! I can feel the happy vibes going on around your nutsack. That even may be a 'Ball Bunyan That Smiles Back!'

Donny: GET THE CAMERA MAN!!

sack in the back

The act of a male tucking his penis and balls between his legs (in a Buffalo Bill type style) while turning around, bending over and exposing his ass with bulging sack to passersby.

As my roommate Jim returned from the shower, he tried to gross me out by performing his "sack in the back" routine in my presence.
