When you're on Facebook Messenger and you accidentally hit the "thumb's up button, usually at the worst possible time.
It's going to look something like:
Person: "I'm having a really rough day"
Me: "What's wrong?"
Person: "My dad passed away. 😰"
Me: "👍"
Me: "Goddammit! The unintentional thumb strikes again! ...sorry for your loss."
Example two:
Person 1: "How are things with the hubby?"
Person 2 :"I found out he's cheating on me."
Person 1: "👍"
Person: "I'm having a really rough day"
Me: "What's wrong?"
Person: "My dad passed away. 😰"
Me: "👍"

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.
