1. noun An informal meeting or conference, especially in order to brainstorm, discuss, or review something. A somewhat flippant allusion to the traditional gatherings held by Native American or First Nations tribes, the term could be considered offensive by some. I think all the departments need to have a powwow together to go over what went wrong on this project. Good, let's have a powwow and see what we can come up with.

2. verb To hold such a meeting. We're going to powwow on Monday to go over the final details.
