1.
A person who is not a Police Officer but believes himself/herself to be friendly with Police. Usually drunk and/or a douche bag stumbling form a bar. The "cop-cop" will approach a police officer or group of officers and attempt to strike up a conversation about police work believing that he/she is accomplishing an original or exceptional feat by asking what they believe to original or endearing questions.

The "cop-cop" can also be a security guard or other wannabe type. Often the cop-cop is not a wannabe or someone with a genuine interest or question but someone being a smart ass or believes himself to be clever, daring, or funny.
