Turtle-back Sack

When a males scrotum is hard like a turtle's shell.

Man, these tighty whities gave me a turtle-back sack.

Sack from the back

When your man ain't acting right...so you grab his nuts and squeeze from the back.

I'm pissed... he deserves the sack from the back.

Around the back sack pack

Another word for a male's jock strap

Did you purchase your around the back sack pack for the upcoming game?

Sack Back

When someone gives you a piggy back ride and your balls are on their back...raw.

I was drunk in the shower and fell. He gave me a piggy ride to the ER then I gave my friend sack back on the way there.

Back Sack

Male equivalent of the side boob. When someone gets a glimpse of your sack from behind. The worst angle to see balls, which are quite frightening at any angle.

That asshole Carl tricked me into looking at his back sack yesterday!
