What does pumper mean?
Pumper is a noun for someone who operates pumping equipment, especially the worker responsible for an oil or gas well, or for a device that moves a liquid, gas, or other substance. In petroleum work, the term usually names the person who tends a well's pumps and manages the movement of its output. An older, chiefly American financial sense refers to someone who promotes a stock, often by trading in a way that creates a false appearance of demand. That use is generally disparaging and sounds historical or specialized today. Because the underlying word pump plainly indicates the action, pumper is especially transparent: the person or mechanism literally does the pumping. The term is most useful when precision matters, as when distinguishing the worker who operates a well's pumps from other members of a production crew. In general writing, it can sound occupational and regional because many readers encounter it mainly through oil-industry usage.
