If polite burps are socially acceptable why not passing gas?
I am one of those people who think farting is hilarious and fun. My nephew and I tell each other we love the other more than farting. But he's just turned five so it is still cute.
I'm usually the one who breaks the passing gas first in a relationship too much to the laughter of the man I am with.
It's great that China is so loud. No one hears anything and it is socially acceptable in most rural parts of China to fart without grossing people out. I get hushed and told I am rude for giggling, pointing and saying "that's only a two out of ten I think you could do better!"
