When you mess up something, whether it be playing a wrong note when playing an instrument, getting a voice crack when you sing, or anything else. You just want to run away. It's so embarrassing and people don't know how embarrassing it can be.

Me: -Voice cracks- EEP! 0~0

Person: No no, keep singing! It's fine

Me: -Curls up into a ball- Nooo it's not, nggggh-
