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.
