hard sack

when you go at it so hard that your balls get hard as well. the thrusting & smashing that goes on for hours becomes so exhausting. you stand there, in & out. when you finally release your steamy, hot, cum it shoots through that pussy & that shit becomes a flapper. the moans are immaculate, echoing off the walls around you. after this type of orgasm your nuts will never be the same. & the chick you smashed will have a grandma cooch for life.

zoe: dude i smashed andrew so hard last night, he gave me a flapper! turns out at the end of that, he had a hard sack!!
theodore: mmm

Sack Shift

If you look closely at your testicular pouch for just a few minutes you will notice subtle movement of the skin your not in control of. Must be done sitting or laying down.

Employee: Sir, you have to leave the movie theater
Me: Shut up! I'm trying to watch my sack shift

Velvet Sack

A soft, smooth, shorn scrotum.

Rachel loves my velvet sack.

I teabagged her with my velvet sack.

It’s a lot of work maintaining my velvet sack. If I don’t I’m like a Sasquatch down there.

sack swipe

To give your scrotum healthy swipes of a stick of deodorant between your nuts and thighs.

I knew I was too late for a sack swipe when I dropped my shorts to urinate and could smell my own nuts.

cactus sack

After a man has shaved his sack and it begins to grow back producing stubble resembling the prickly bits of a cactus.
