Zombie Thumb 

Zombie thumb is when you wrap your thumb, while wearing a splint, in a plastic bag while you exercise to prevent your splint from smelling like sh1t. The end result is an extremely wrinkled finger thats pale white with a ridiculous looking tan line

Wrapped my thumb in plastic to go for a bike ride and came back with a zombie thumb.

thumb zombie 

A person that idly scrolls through social media on a mobile device, often without even paying attention to the content. In extreme cases hours can be lost in this state. Interaction of any kind is impossible, one must wait for either a wifi drop out or battery low warning before engaging.

"Sue! You're such a thumb zombie, look at me when I talk to you!"
