A contest or fight involving womens breasts. There are several variations including Hands On, No Hands, and Titboxing. In Hands on, the women place their hands on their opponents breasts and squeeze until one submits. In no hands, the women use only their tits to fight, either bumping breasts, simply mashing together, or bearhugging until one submits. Titboxing is a variant of no hands except that there is no use of the arms at all either for leverage or bearhugging.
Two women are interested in determining which has the best breasts. They decide to determine which is the best with a no hands titfight. They battle until one or the other submits and admits her opponent has the best chest.
