1. A sac (bag) of any kind. Could be a backpack, a purse, a plastic bag, a bag for testicles, or any kind of bag/device that holds stuff. See example #1.

2. Loosely used to describe anything. Also used as a suffix for one's name by a small, cultish group of linguists residing in the nation's capital. See example #2.

3. Inserted innocuously into sentences as a substitute for words rhyming with it. See example #3.
1. "Did you hurt your sac?" "I sho' did!"

2. "How's your sac?"

3. "I'll be right sac."
