A euphemism for inviting someone over to their place to engage in sexual activity. Thus the expression, "let's Netflix and
chill!" should be understood by the hearer as "let's come over to my place and fuck!" The
genius of this phrase is that it gives both parties "plausible deniability" when its true meaning is prematurely exposed so no one has to lose face (the inviting
party can
say, "I was just talking about watching movies and hanging out" or the invited party can say, "You're talking about watching movies and hanging out, right?")
