The noise created while sucking through a straw at the bottom of an empty drink, it represents the need of a refill.

Ahh man my straw is makin cup chatter, I need to go get a refill
When your drinking a soda from MacDonalds or some resturant that has straws and you here the noise (Cup Chatter), right when you here it you know you need a refill
