What does dobber mean?
Dobber is an informal noun with several distinct meanings across the English-speaking world. In British English, particularly in northern England, it most commonly denotes a foolish or clumsy person — an insult that is usually teasing rather than cruel. In Australian and New Zealand slang, a dobber is someone who informs on others, a telltale whose behaviour is strongly frowned upon in cultures that prize loyalty among mates. A third, older sense survives in angling, where a dobber is a float that signals when a fish has taken the bait. The word derives from the dialect verb 'dob', meaning to drop or place something down heavily, which also underlies Australian 'dob in'. Its tone ranges from affectionate banter to genuine reproach depending on context.
A foolish or stupid person.
"You left the keys in the ignition again? You old dobber."
Chiefly British and northern-English informal; often affectionately mocking rather than hostile.
A person who informs on others; a telltale or snitch.
"Nobody trusted him after he turned out to be a dobber."
Australian and New Zealand slang; carries strong social stigma.
A float used on a fishing line to indicate a bite.
"He watched the dobber dip beneath the surface and struck too early."
Regular plural; used for all senses.
"The lake was dotted with the dobbers of a dozen anglers."
In Australia, calling someone a dobber can get you ostracised — there 'dobbing' on your mates is close to the worst social crime there is.

Etymology of dobber
Dobber derives from the dialectal English verb 'dob', meaning to drop or thrust down, itself probably of imitative origin from the early seventeenth century. The agent-noun form came to denote both a thing that bobs or floats — hence the angling sense, paralleling American 'bobber' — and, figuratively, a person of little account. The Australian informer sense developed from the phrasal verb 'dob someone in', attested by the twentieth century.
How dobber is actually used
Informal and mildly insulting but generally light-hearted rather than vicious, especially in British usage where it often implies affectionate exasperation. In Australian and New Zealand English the related verb 'to dob (someone in)' and the noun 'dobber' carry stronger stigma, since informing on peers violates the local ethic of mateship.
