The act of watching Netflix and being really good at it. Not just anyone watching Netflix can Netflex. It requires commitment, having a special eye for good shows, and being able to binge watch with control.
Person A: Hey wanna come out tonight? Gonna be lots of chicks and beer.
Person B: Sorry bro, can't tonight. You can't catch me straight Netflexing though.
NextFlixing is when you endlessly cycle through the movie and TV titles on a streaming service finding stuff you're not interested in or want to watch just not right now. This is normally followed by settling on something you've already seen and falling asleep moments later.
"Last night I spent an hour NextFlixing before deciding to watch the same episode of Star Trek I have seen 100 times."
The act of making a business decision so misguided as to border on absolute stupidity, leaving everyone else to wonder what the hell you're thinking.
Steve: Hey, Joe! Nice work on raising prices by 60% and changing the name of one of our most popular services to something stupid. You've really been Netflixin' it lately!
Joe: Thanks, Steve! I was thinking of also introducing the rebrand to our customers via an apology letter.
