My DC is 11 and constantly mentions poo in conversations. Not real physical poo itself. But just weaves the word into conversation.
Examples:
You stink like poo
I'm going to poo on your head
That's a big pile of poo
Poo on you
If you do that I'm going to poo on you
Etc
The list of examples can go on and on. It's usually just weaved into every day conversation, but countless times a day. I don't know what to do about this. It seems to be an involuntary thing and doesn't stop no matter how many times we ask to stop. DC will often become infatuated with different phrases and for the past month or so it's poo. DC uses these phrases when talking to friends and family. There is no filter. No matter how many times we ask to stop it continues. And now to make things worse my youngest DC is copying them and picking up on this and using the same phrases. It's so embarrassing.
Any advice please? I'm at my wits end with this.
