noun
- A confident statement involving openly acknowledging shortcomings, demonstrating indifference to others' opinions.“But first, a refresher. The underbrag is a post-brag-brag, post-humblebrag form of bragging. It's the third wave, if you will. It is when you announce boisterously your mistakes and foibles, regardless of your fears of being judged, shamed, punished, or fired.[…]Ideally, the underbrag is also funny in a self-deprecating way, and possibly empowering, but never sad.”
