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."

Get the disposable thumbsmug. The sexist rule schools follow, forcing female students' shorts to go to at least their thumbs, making it almost impossible to find an acceptable pair of shorts.
Teacher: Miss, your shorts don't follow the thumb rule.
Girl: They're the longest I could find.
Teacher: They're distracting the boys in the class.
