A "tournament held on friendly, non-destructive, terms in which participants wore padded garments of *bumbace, using lightweight weapons made of *baleen. It was intended as an exercise in skill, judged by scoring points. Tournaments were only allowed under licence; one such held in 1226 occasioned a writ, in which the Latin form of behourd was used: buhurdicio.
