the immunity you get from your parents for whatever they know about your sex/dating life because your brother or sister is gay
My mother would never let my boyfriend and me sleep in the same room at her house except for the gaymunity I have from my lesbian sister.

My parents have stopped lecturing me about "living in sin" ever since they found out the truth about my brother's "roommate"; I love the new gaymunity.
