Is a trash bag that is full of normal trash and puke but doesn't throw it away and then someone goes to throw something in the bag that might cause the entire bag to tip over causing a disgusting mess.
When you puke in a trash bag and someone goes to throw something away on top of it and you go to stop them by saying, "No, don't do that. That's unhappy trash."
