Companionship between two cousins (or cuz-faces) that is so intimate, it borders homo-eroticism. The most common sightings of this big ol’ gay bond in action typically occur in 2-man team sports. Playing/mating patterns of the cuzband are similar to that of the mourning dove – one per lifetime.
Hoss: Say, Lil' Gary, would you like to join me for a bout of horseshoes?
Lil' Gary: No thanks, Hoss, I only play 2-man team sports with my cuzband, Luis. We are the epitome of cuzbandry.
