sack slip

When a testicle (more often than not, the skin covering the testicle) slips out of an article of clothing, partially or fully, and is noticed by someone else.

When he was being interviewed by Mo his shorts were too loose and when he crossed his legs everyone to their horror witnessed the sack slip.

sack syrup 

The slimy sweat build up on your sack crevice from sitting in one position for an extended period of time. A combination of sweat and stench molecules.

After watching 2 series of breaking bad my sack syrup smelled rancid.
