Cussing Police

Someone who gets pissed or annoyed when you cuss near them.
They'll likely tell you to stop cussing, because 90% of the time they're just a sensitive snowflake.

Guy A: This burger is SO damn good. I can't fucking believe it.
Guy B (Cussing Police): Don't say that! Cussing is offensive!
Guy A: Shut up dude, am I not allowed to say a cuss word anymore? Sounds like someone called the cussing police!
