What does upsetter mean?
An upsetter is a person who overturns or unsettles an established arrangement. The term once had a strongly political sense, describing a radical or revolutionary portrayed as disrupting the prevailing order. It can also be used more narrowly for a competitor that defeats a favored opponent, although spoiler is now the usual sporting label. As an agent noun, upsetter is built directly on upset: the basic idea is someone who causes a reversal, disturbance, or defeat of expectations. The word is relatively uncommon in everyday speech and often carries a faintly challenging or confrontational tone, especially when it labels political dissenters. It is nevertheless more pointed than the neutral phrase person who objects because it implies active disturbance rather than mere disagreement. Understanding the word clarifies its compact contrast between an action and the person responsible for it.
