Four thumbs

When you type so fast it looks like you have 4 thumbs
Like in anime/manga, they put multiple fingers to show the speed of the characters typing (with an addition of movement symbols like "《" "//" "=" ect...)

Person 1: typing
Person 2: "do you have Four thumbs or summ"

Thumb Promise

A Thumb Promise is a promise stronger than a pinky promise. It shall never be broken, and if so, then the person who broke it may never be trusted again. Crossing your fingers does not invalidate a thumb promise.

“She thumb promised me she’d get me a drink if i called mom upstairs for her.”

Fast Brain Slow Thumb Syndrome

The acceleration of typing speed but deceleration of the accuracy in the words , content and context while texting due to thumbs fatigue although thought flows are exponentially high. Also known as FBST syndrome.

I was texting this girl come over to my room but instead I got hit with Fast Brain Slow Thumb syndrome and wrote “Come Over my hoes” so I blew my chances.
