deja viewing 

The terrible feeling you get when you're half-way through a movie or a program and suddenly remember you've watched it before, and thus realize that your evening is shot, your memory is a sieve, and your whole existence is a waste. A byproduct of too much streaming in too concentrated period of time.

Oh, dude, I was killing it with Steve McQueen and Bullitt and then it hit me I was deja viewing and had just seen it like, a month ago.
My sister is locked in a loop where she keeps deja viewing stuff and then gets all disgusted with how bleak her life is.
I've seen Pulp Fiction about a dozen times on purpose, but unintentionally deja viewing The Great Train Robbery just once left me totally bummed.

Dejaviewing

When a character in a TV or Movie pays homage to a character they previously played. Also can be coined when the show itself gives props to someone related to the show. Can also be used in Future context: During the Buffy series, there are no less than ten references to the Avengers comic books, and Xander even says "Avengers Assembe" twice. Later, the writer and director would go on to create one of the top-grossing films of all times, The Avengers.

Dirk Benidict playing Face from A-Team recognizing a Cylon in passing. He was totally Dejaviewing. Nathan Fillion as Castle dressing up as Captain Malcolm 'Mal' Reynolds from Firefly. In Burn Notice, someone called Bruce Campbell's gun a boom stick.
