What does dumper mean?
A dumper is, at its core, something that dumps — an agent noun built directly from the verb 'to dump.' Its dominant modern use names a vehicle fitted with an open, tilting body used to haul and unload loose material such as soil, gravel, sand, or demolition rubble. Small versions of these machines, often simply called dumpers, are a familiar sight on British and Irish building sites, while in North America the equivalent road vehicle is more commonly called a dump truck. By extension, the word can describe any person or device that discards or empties things, from industrial waste handlers to, informally, someone who ends a romantic relationship — the counterpart to the 'dumpee.' The word is plain, functional, and largely neutral in tone, belonging to the everyday vocabulary of construction, waste management, and casual conversation rather than formal writing.
A vehicle or machine with a tilting container for carrying and unloading loose material such as soil, gravel, or rubble.
"A mini dumper ferried bricks along the narrow path behind the house."
In British English this typically denotes a small, open, four-wheeled site machine; in American English the road-going equivalent is usually called a dump truck.
A person or thing that discards, abandons, or empties something out.
"He joked about being the dumper in every breakup he'd had."
Often used informally in contrast with 'dumpee.'
(Informal, chiefly US) A container into which refuse is dumped; a garbage bin.
"Take those boxes out to the dumper before the truck comes."
Regional and colloquial; less common than 'trash can' or 'garbage bin' in most American dialects.
Regular plural; standard for both the vehicle and person senses.
"Three dumpers were working the site before dawn."
On British building sites, a 'dumper' is the little open-cab workhorse that has shuttled sand and rubble since the mid-twentieth century — and in dating slang it is also the one who ends the relationship.

Etymology of dumper
Dumper is formed by adding the agentive suffix '-er' to the verb 'dump,' which itself appeared in English in the early eighteenth century, probably of Scandinavian origin (compare Old Norse 'dumpa,' to thump or fall heavily). As machinery developed in the nineteenth and twentieth centuries, the agent noun was applied to vehicles that dump their loads, giving rise to the site dumper familiar on construction sites. Closely related formations include 'dumpster,' a twentieth-century American coinage blending 'dump' with a trade name.

How dumper is actually used
The machine sense dominates in construction contexts and is especially common in British English, where 'site dumper' refers to the small articulated vehicles used on building sites; American English more often says 'dump truck' for larger road-going vehicles. The informal 'person who ends a relationship' sense usually appears alongside 'dumpee'.
