The feeling you get when you see someone that you think you know or have met before but can not bring the name or how you know them to mind.
I'm sorry for staring at you for so long, but I'm having the worst case of deja you. Don't I know you from somewhere?

That moment when your watching a youtube clip and while reading a comment quoting a section of the clip, you read what you're hearing.
While watching a youtube clip on a Football Family Meltdown, Jerry yelled as I read "Look at Romo running like a god damned idiot.", creating this paradoxical déjà you for those three magical seconds.
