Top definition
A complete idiot, a yobbo, a bogan, a redneck, a simpleton. Lacks culture, usually in the lower socio economic demographic, and is sheep like in the way they follow everyone else. They believe everything that is trotted out to them via the media.
This neighbourhood is full of dundersons.
His dunderosity is exceeded only by his ugly looks.
