When a man's scrotum is so hairy it resembles that of a Lumberjack's beard.

You have a Lumberjack Sack, it looks like the Brawney paper towel man.

back sack attack

The assault of one's testicles from behind. Generally, the victim is bent over, however a standing attack up the legs is also commonplace.

Often times, the assailant will yell "back sack attack!" either at contact, or after the strike is complete.

Winding up for a kick, Ben positioned himself behind a bent-over Matt. Using mostly the flick of his foot unto the scrotum, Ben yelled "Back sack attack!" before Matt ever got the chance to react. Devolving into his fetal position, Matt sat writhing in pain.

Double Sack Taint Smack

When two guys are fucking the same girl, one in the front and one in the back, and their timing gets messed up leading them to smack eachothers balls on the girl's taint

Me and Jim were fucking this chick the other day and he screwed up the timing and we ended up doing the double sack taint smack!

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.
