Burners usually refer to a fire festival as a "burn." Both "burner" and "burn" are derived from the common practice of creating, erecting and displaying a piece of "burnable art," or a "burnable art installation," at a fire festival. Ultimately, these art pieces are set afire and burned to ashes as an artistic experience for everyone present. Indeed, all burns climax with the informal but time-honored "ritual burning" of a large, wooden effigy and/or art edifice on the final (and/or penultimate) nights of the burn.
"Oh yah, I've been to the Playa a few times now, and a couple regional burns back east."
