As a teacher in a high school,9-12,what's the best way to handle a student calling/yelling F*G in the hallway?

I'm a 9th grader and I know what you are talking about. Those words are used day in and day out. I hear them everyday at school. I guess you can try to talk to them and tell them that those words are unacceptable to be used in that kind of manner. If the students have any type of respect or any maturity within themselves, they will stop. I can't promise that they will stop because like the person above me said, kids are kids, and they might just take it as a joke and move on with their day. Good luck.
