警痞
[jĭng pĭ]
The term '警痞' combines the character for policeman ('警') and rogue/troublemaker ('痞'). It could describe a cop who isn't entirely by-the-book, perhaps one with a rough-and-tumble attitude or unconventional methods. This might appeal to someone who admires antiheroes in police roles, embodying a cool yet rule-bending enforcer of law.
