What is the name of the secret society featured at Yale in Gilmore Girls?

The secret society featured at Yale in Gilmore Girls is the Life and Death Brigade.

The Life and Death Brigade is an eccentric, invitation-only group associated with Logan Huntzberger and his wealthy university friends. Its members stage elaborate events and embrace risky theatrics, making the society a symbol of privilege, rebellion, and Logan's social world.

The group takes its name from a fictional organization in the 1945 film The Private Affairs of Bel Ami, which itself was based on Guy de Maupassant's novel Bel-Ami. Gilmore Girls uses the name for a more stylized campus society built around spectacle and exclusivity.

The Life and Death Brigade is not the Yale Daily News, where Rory works, and it is not a real official Yale society portrayed as a documentary fact. It is a fictional element used to expand Logan's character and challenge Rory's usual caution.
