It's a term used to describe diehard Apple zealots who think Apple invented everything.
Now look, I'm not here to bash one's preferences. If you like iPhones or Macs, then whatever, that's cool man. You do you.
The thing is Apple is hardly what I call "innovative". What they're good at is iterating on the innovation of others and packaging it up nicely for the public to consume, with a very simple, not-intimidating interface.
Even with their latest, the iPhone X, hardly could be considered "innovative". Android phones have been pushing for the bezel-less screen before Apple (earliest I can recall is the Aquos Crystal by Sharp back in 2014, which had zero bezel on the top, left, and right sides). Facial recognition has been a feature of Android since 4.0 "Ice Cream Sandwich" (2011). It's not to say that the iPhone X isn't good at what it does, just that it's hard to honestly call it "innovative".
