Nudecular Deterrent

When two individuals possess nudes of each other, assuring any leakage of one parties nudes to the public will result in a retaliatory leakage, aka mutually assured humiliation.

Person 1: Are you sure sending nudes to them was a good idea? I heard they put their ex's nudes in a group chat.
Person 2: Psssssshhhh don't worry they won't. They know I'd just leak out their nudes. I got that nudecular deterrent!
