I wonder sometimes if Netflix made this expression a meme for its advertising value or if it just came about as a natural meme

How do you know that's not what he meant?

I learned of this euphemism one night at our family dinner table, when I suggested to our teenage kids that we all take some time after dinner to "Netflix and chill." Needless to say, they were a bit surprised by the suggestion. :)

Maybe a more apt term would be polymath porno.
