Do not say, "fart!"

Hey there! Did you know that some people think "fart" is a gross or even impolite word? Well, I've given "fart" a lot of thought and I'm here to help! I've come up with some other choices so that when you are out and about and someone let's it out, you do NOT say "fa--!" Phew! I almost said it again. Do you have a favorite word that you use instead of "f---?"
