gadgetonanist
A gadgetonanist is like a geek on steroids. They love gadgets so much they'll talk about them until you're ready to scream.
'This phone has 5 cameras. You have 1. You’re not even cool.'
'I just bought a fridge that tells me when my milk is going bad. You still use a paper list.'
'You don’t even know what Bluetooth is. I’m surprised you still use a landline.'
