naggery
Naggery is when someone acts like they're the only smart person in the room and won't stop telling you how dumb you are. It's like being yelled at by a know-it-all idiot.
My brother does naggery all the time. 'You're stupid!' 'You're lazy!' I'm gonna hit him.
My friend does naggery in group chats. 'You didn't reply!' 'You didn't text me!' I'm gonna block her.
My mom does naggery at breakfast. 'You didn't brush your teeth!' 'You didn't eat your cereal!' I'm gonna throw my cereal at her.
