The Know It All Neck Beard is someone everyone has met at some point on the internet. You know the type. The guy who thinks that they know everything and will not be convinced otherwise. The guy who, even if they don't know it, will go to the bathroom just to look it up on Wikipedia to shove it in your face later. Everyone loves those types of guys.
This is a collection of the Know It All Neck Beard meme. A photo meme of a smug bearded nerd with captions describing how much more he knows then you.
