Gadgetist
A gadgetist is a person who thinks they’re cool because they have all the latest gadgets and everyone else is a tech dummy.
"I have the newest phone. You have a phone from 2010. You're a fossil."
"My phone can do 100 things. Your phone can do 1 thing. You're a loser."
"I’m cool because I have a phone that can take photos. You're just a normal person."
