Someone who goes around thinking things are big and clever, and believe they know it all about everything, but don’t because their still things he / she don’t know about just yet.

Person typically has one button and it’s their way or nothing else. Don’t disagree with a know it all because if you do your entire day will change. They will quickly flip the script and could even lead to hate crimes, or even worse the “ K bye”

Tim: oh, look at that white cat, it's so cute!
Jim: what white cat? I can't see any white cats here. Oh, you mean the white cat with some grey dots on it's forehead? Cause that isn't a white cat. That is a semi colored cat....
Tim: can We just warm up some noodles night? I feel like eating something easy, the japanese way.
Jim: uhm, noodles are actually chinese and not japanese, just so you know....

Someone thinks they know something but are totally wrong. They will argue with you even when proven wrong.
