I have taught my children terms like "Bad Girls" that they use in place of bad guys. Teachers are stunned and my son and daughter correct them.

You see after teaching them this the first time they saw a cop arrest a woman and drag her to the car. The cop then walked up and said hi and my son said "you caught the bad girl", which the cop replied "yes I did catch the bad girl" and gave them both gold badge stickers. HAHAHA
