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.

I could smell Tims sack syrup from over here after he completed gta 5.

Yesterday, my mom caught me doing the sack clack and she started to join in and she was really good at it!
