Boycott
Etymology
From Captain Charles Boycott, an English land agent in County Mayo, Ireland, in 1880: after he refused to lower rents and pursued evictions, the Irish Land League organized the community to shun him — laborers quit, shops refused service, and mail went undelivered. His name became the word for that tactic within months, in multiple languages. It is one of the fastest coinages from a living person’s name.
noun · /BOY-kot/
An organized refusal to buy from, deal with, or participate in something as a form of protest.
What it names
The standard term for collective economic and social withdrawal used as leverage.
Example
Consumers organized a boycott of the brand over its labor practices.

A boycott withholds your custom to pressure a target; a strike withholds your labor — both are collective refusals, but of purchasing versus of working.
