I'm looking for a slur or an insult that'd describe a person who appears over-zealous about her job. More specifically, it's a situation where a cop arrests a suspect and has just handcuffed her. She wrenches the suspect along with quite a bit of force, and the suspect calls her out on that. The accusation would sound something like this: "Watch it, ____ ! You almost dislocated my shoulder there!" The suspect is also supposed to be a bit of an annoying brat there. Suggestions? I haven't managed to come up with anything that'd fit that context ._. Thanks in advance!
