What does pesterer mean?
A pesterer is someone who repeatedly annoys, bothers, or asks for something, usually with tiresome persistence. The word is informal and often mildly disapproving, suggesting that the person's behavior is not serious or genuinely important but is difficult to stop. It can describe a child who continually asks for another helping of food, a colleague who keeps pressing for a decision, or anyone who follows another person with unwanted requests. A pesterer is therefore defined less by the intensity of a single incident than by the annoying persistence of the behavior. The term is useful when describing a person whose repeated demands or questions create friction or make a situation difficult. It belongs mainly to everyday English and is common in both British and American usage.
