Gadget-Gollum
A human who acts like a feral animal when a new gadget drops. They'll scream, cry, and probably pee on your shoes if you don't let them buy it.
I saw a new phone come out and I literally threw my old one out the window.
I woke up at 3 a. m. to check if the latest smartwatch was on sale.
My friend got a new VR headset and now he thinks he's a wizard.
