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.

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
