Honeywagon (vehicle)

A honeywagon or honeycart is the slang term for a "vacuum truck" for collecting and carrying human excreta.^[1] These vehicles may be used to empty the sewage tanks of buildings, aircraft lavatories, passenger train toilets and at campgrounds and marinas as well as portable toilets. The folk etymology behind the name 'honeywagon' is thought to relate to the honey-colored liquid that comes out of it when emptying the holding tanks.^{[citation needed]}
