An annoying sibling. For example, like my little brother, Angel, busts in my room without knocking and starts jumping on my bed and throwing things everywhere.
Person 1: MY LITTLE BROTHER IS SUCH AN ACKBUG he opens my door without knocking and always asks me to do things for him when there are people right next to him and they're not doing anything at all!!
