honeydew dipper
A person who would use a bucket on the end of a rope to dip into a cesspool and remove "honeydew" (raw sewage) to transfer to a container (usually a large wooden barrel) on wheels and remove from premises and dump elsewhere. Late Victorian euphemism. Also, slang for a stupid, unskilled person; similar to a "ditch digger."
He's so unskilled he'd have difficulty finding a job as a honeydew dipper.
