naggery
Naggery is when someone acts like they're the most important person in the world and won't stop talking about how great they are. It's like being stuck with a loudmouth narcissist.
My teacher does naggery in class. 'Did you do your homework?' 'Did you finish your test?' I'm gonna sleep through the next lesson.
My neighbor does naggery every day. 'I have the best lawn!' 'I have the best car!' I'm gonna throw a rock at their window.
My cousin does naggery at family reunions. 'I'm the best at everything!' 'I have the most friends!' I'm gonna fake a stomachache.
