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.

When you're on Facebook Messenger and you accidentally hit the "thumb's up" button, usually at the worst possible time.
"I'm having a really rough day"
"What's wrong?"
"My dad passed away. 😰"
"👍"
"FUCKING UNINTENTIONAL THUMB! Sorry about your loss."
Or ...
"How are things with Robert?"
"I found out he's cheating on me."
"👍"
"So sorry, the Unintentional Thumb strikes when you least expect it."

A hand gesture used while reasoning out very complicated topics, especially when studying Talmud. The speaker does a kind of diagonal thumbs-down and then dips and turns their thumb in a half-circle so that they finish with the thumb pointing up.
Is the nighttime prayer optional or mandatory? If (*thumb dip*) the basis of the daily prayers is from our three forefathers, then the nighttime prayer has the same importance as all the others, and so it's mandatory. But if (*thumb dip*) the basis of the daily prayers is the offerings from the Temple, and we know (*thumb dip*) that no offerings were brought at night, so the nighttime prayer must be optional.

rotating the wrist with hand out straight so that the side of the tumb bangs on a desk. In a thumb thumb this is done twice in succession. This is used by teens taking their exams to signal to others around them they are finished and bored. This usually recquires another thumb thumb as a ressponse to show that it is understood and that the second person is also finished and bored.
