No, not stupid...it even took me a while to learn what it is.

On a bong, there's two ways to create the suction needed to draw in the smoke. Some bongs have a small hole on the rear that you cover as you draw in to create the suction. Others have a removable stem that creates suction when it is placed in the bong so you can pull, then removes that force when you pull the carb from the bong.
