Preparation for Battle: The Cherokee had many traditions in olden times to prepare for battle. They did not eat before a battle. They took a long bath. They drank special tea. And they danced at the Booger Ceremony.
Booger Ceremony: The Booger Ceremony was held on the day before a battle.
All the warriors wore the booger masks they had carved. They danced around and made fun of each other. The masks represented their enemy.
