Pheonetic spelling of bubbler as used in the speach of residents of New England, principally Boston. Describes a water fountain. Not the type of fountain that can be found in school hallways and in hospitals, among other places, but the ones which have a 5 gallon tank on top. Name comes from the large bubbles which form and rise to the top of the bottle when the spicket is used.
Vinny, you'd better throw another poland spring on there before that bubbla is kicked.
