Yes, under no circumstance say a really foul word like snickerdoodle !
Jokes aside, that seems to be the solution for this problem. Choose one or two fairly unusual (but innocuous) words, and act like they are super nasty. When the child repeats it, act surprised and disgusted. Every time he repeats it tell him sternly that it is nasty.
Because the child doesn’t really know what is bad and what not. he only cares about the reaction he gets from you.
