Sack Breath

Someone who has major dog breath and it smells as though they’ve been licking their own scrotum. Hence, producing a “from-unda” type sack breath, so bad it would cause even “Broom-Hilda” (1,500 year old cigar 🚬smoking, beer 🍺 guzzling, and cheeseburger eating witch) to cringe at the foul stench.

“Even stink would say that stinks, he’s got major “Sack Breath!”

Smackin' the Sack

1) The act of constantly abusing your genitals to pleasurable thoughts
2) Slang for playing the game of Hacky Sack

1) "Jeff's kinda weird, he says that instead of masturbating, he usually just smacks the sack."
2) Man 1: Hey what are you doing?

Man 2: Nothin' much just smackin' the sack, you want in?

Man 1: Sure!

Paper membrane sacking (PMS)

Two females performing 69 underwater, using each other's vaginally cavity as a re-breathing apparatus.

The girls enjoyed paper membrane sacking (PMS) in the Caribbean waters more than snorkeling.

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!
