There's an unbreakable vow when dating someone that requires a couple to watch their favorite show with each other at the exact same time. You can't go further on your own and if you do, you commit the worst act imaginable - NETFLIX CHEATING!
Netflix defines it as "watching a TV show ahead of your significant other," and it has increased to over 48% of all couples in the US having done it at least once. The top shows this happened to were Orange is the New Black, House of Cards, Daredevil, Stranger Things, and Narcos.
