sack weld

When it is so hot and sticky that your nut sack is hard welded to the side of your leg that it requires a pry bar and a full on split to separate them.

Dude i was in New Orleans this summer and the sack weld was so bad it tore the hair off my legs.

sack rake

The act of raking the underside of your partners sack for pleasure. Turn your palm upward and set your fingers in order to create a ‘bear claw’ pose. Plant the ‘claw’ at the base of the nut sack and scratch forward. Plant, Rake, Repeat. The act is concluded upon your partners climax or aborted at the first hint of blood. Great for a tired, sweaty, itchy sack.

Steve came home from work after a tough day. Bill suggested a sack rake. Steve accepted and Bill DELIVERED!

Bang Sack

A rogue walmart bag floating around the parking lot that a lonely freak stumbles upon and mangles it into a practically non-existent jizz dumpster. Very practical and quite useful as a bartering chip at local pawn shops.

Nathyam: I really want that buttplug you got behind the counter but all I have is this BANG SACK
Tyler: I've never seen a finer piece of merchandise in my life, you got any more?
Wheep: WOW! how neat, I'll have to find me one of those beauties.

SACK Principle

A principle that is used to determine if a side bitch or FWB situation is getting too serious:

-Sleeping over
-Asking to be exclusive
-Cuddling
-Kiss goodnight

If all four criteria are met at different points in the fling, you may have a relationship on your hands.

Are you sure you and her are just FWBs? Didn't you stay over at her place last night? You better watch out, that's one of the SACK Principles.

Yo dude you've met all four points of the SACK Principle! She totally wants you to ask her out.
