A sausage pact is a polygamy consisting of only guys. The structure of the marriage differs from group to group. For example, one sausage pact may have a rotational alpha-male, while others may have a traditional alpha-male. The sausage pact is related to the sausage party or sausage fest.
Hey Alex, congratulations on your sausage pact, send my love to your husbands for me!
