I have different names for my iOS devices: the 5th gen iPad is "Madam Susan's Greater House of Pain," 6th gen iPod Touch is "Silverbird," 7th gen iPod Touch is "Reddy1," iPad Mini is "SmallPad" & the Space Grey iPhone SE is "GreyPower."
Thinking of various names for the black 128 GB iPhone SE (2020) that's on its way I don't think I can do any better than "The New Black."
