What is a honey wagon?

A honey wagon is a mobile trailer or truck used for transporting and disposing of sewage waste from RVs, boats, and other places where traditional sewage systems are not available. The term 'honey wagon' is often used because the waste produced in these environments is typically called honey, as a euphemism. The wagon is equipped with tanks that hold the waste, and a pump that empties it into a septic system or disposal facility. The term honey wagon is often used informally to refer to any kind of tank truck used for waste disposal.
