Oh notion sack sorry I used to hear alot of old timers talk about it most of the time in a joking manner. They would laugh about having to add funds to thier notion sack when they would get mad at thier wives lol. Notion is still popular but notion sack not so much. I think because of the economy right now noone has mony to put in a notion sack. Also the old men that really had a notion sack kept it a secret from thier wives or girlfriends like a secret saving account. This is really supported by the way I remember them joking about adding money when they had arguments with thier other half. "If that woman doesn't lay off of me I am going to grab my notion sack and run." as an example. Mad money is another name in west KY for this type of hidden savings. You are saving it to make a "mad dash" from police or your girlfriend or wife lol. This is another old term not really used much and when it is used it is usally by older men. This stuff fascinates me so if you have any other questions let me know.
