Taking advantage of access to another persons iPhone/iPad in private, generally without their knowledge/consent by filling their camera roll with pictures of large/unusual/grotesque cocks without needing to know their passcode.

A successful cock lock requires a second device to perform some strategic obscene google image searches while you access the victims camera from their lock screen (thank you Apple).
