"A rumble is a discussion, conversation, or meeting defined by a commitment to lean into vulnerability, to stay curious and generous, to stick with the messy middle of problem identification and solving, to take a break and circle back when necessary, to be fearless in owning our parts, and (...) to listen with the same passion with which we want to be heard. More than anything else, when someone says, “Let’s rumble,” it cues me to show up with an open heart and mind so we can serve the work and each other, not our egos. Armoring up and protecting our egos rarely leads to productive, kind, and respectful conversations." BROWN, Brené (2018): Dare To Lead. Brave Work. Tough Conversations. Whole Hearts.

Also ich kann mir durchaus vorstellen, dass ein Chef ein Meeting mit "In diesem Sinne, meine Damen und Herren, auf in den Kampf!" beendet.
