Bumpkins are residents of the small country town of Portsmouth in Hampshire. They dress like scarecrows and speak with a quaint rural dialect, using Romany words like dinlo and shant. These poor simpletons are also know as carrot crunchers or worzels.
Look at that pathetic bell-ringing bumpkin in the long blue wig.
Dinlow, or dinlo, is the Romany word for an idiot or fool. It has also been incorporated in the rural dialects of some farming communities, such as Portsmouth in Hampshire, where there is a large gypsy population.
