I think fart is a funny word and very appropriate, in most situations, for a funny, if all too human, activity. However, if I were having tea with the Queen I would apologize to her for “passing gas.”
I say “poot.” It’s one of my favorite expressions for aggravation, too. I did a college paper on the etymology of “fart.” Wish I could remember the details but my prof kept the paper.
Our family never had a term for it…it just wasn’t discussed. I do recall a couple of times that Dad would look at the dog, and in a disapproving tone, say her name. We were all sure he was passing the blame for the noise.
A friend’s family uses a term I had never heard of before. “Mommm! Uncle Bill just stepped on a duck!”
Well I’m in eighth grade and so waaay too many people are immature as you might imagine. So I rarely hear the term passing gas. Its mostly just farts. All day long.
