Know-It-All (KIA): A species of human that cannot be told anything that they haven’t already heard and/or they know better than you at all times, in all circumstances, and will generally defy you with their dying breath. They cannot hear what you’re saying, but merely wait for your mouth to stop moving or texts to stop so they can tell you how/why/what. Narcissists and insecure individuals are known for this particular personality trait. Also, they were probably not breastfed.
1) Tim is such a KIA. He refused to listen when I asked him to please not overload the dryer so the clothes would dry and the motor would not burn out.
2) When Janet heard that her neighbor’s dog needed its anal glands expressed she promptly shifted into KIA mode by demonstrating the proper technique, emailing articles, drawing diagrams and then finally using herself as an example. It didn’t matter that the neighbor was a professional pet groomer, breeder and dog rescue volunteer for the past 20 years.
