look up any word, like the eiffel tower:
 
1.
A syndrome where the thumbs can't be used to text on a smartphone due to over texting.

Unlike carpal tunnel, where the problems occur due to a median nerve in the wrist, Carpal Thumbel is due to a nerve pinching in the hand.
"Kara, why can't you type a text?"

"I can't move my thumbs! I have tingling, numbness, weakness, and pain in my thumbs! Could it be Carpal Tunnel!?"

"No. What you suffer from is Carpal Thumbel Syndrome."
