Toddler potty talk

So to start I know this is completely normal for toddlers/kids and I do NOT want to discourage normal talk about potty related things, but my 2.5 and 3.5 year old have started potty talk. Not just here and there but it’s become all day No matter what we’re playing. Things like “i have smelly poopies on my head.” “I smell like yucky poop” “did you go poopies again on your head” 😩😂 etc. it just gets worse, and they both find it so hysterical and do it to be funny. I’m a sahm that obviously never says these kinds of things so I know it’s just normal kid stuff they’re making up, but I don’t know how to properly tell them they can’t always talk like that (they do it in public too). I don’t want them to not think it’s normal to talk about regular potty things. I personally have never been comfortable talking about those things even now in adulthood and I don’t want that for my kids lol. I just want to tackle this before it gets out of hand. Any advice?
