You need a bung hole!
PS - the term "bung" comes from the plug that is hammered into a wine cask or a beer barrel. "Bunghole" was not coined by Beavis and Butthead, or even MTV. It came from the brewing/winemaking industry.
Way OT
Yrs ago I heard there was a Liquor store called "Bunghole Liquors." How would you like to have to answer the phone like that.:rofl:
