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.

straight from the sack 

The art of drinking goon(white wine) straight from the sack/cask, instead of behaving like a civilised human and drinking it from a cup.

"She was so drunk, she started skulling straight from the sack!"

Hanging from his sack

Commonly refers to women, in a work environment, that overly display favoritism towards certain male associates in a pseudo sexual manner. To overtly fawn over a male associate/ be overly friendly.

John is standing at the copier. Mary and Sue go up to John and flashing their smiles openly flirt with John and make riddiculous small talk. Kathy sees this and states to Bob who also had to endure this and exclaims...Wow they are feally hanging from his sack

frog sack

An odd package of a male where the package does not touch any part of the body. There is no shaft just a tiny head that looks like the head is attached to the sack. The sack has no excess skin-the skin is tight against the balls. It looks like a frog.

The 5 year old had a frog sack.
