As long as you don’t do it right in my face it’s all good. I understand suppressing or muffling it in close quarters or formal situations. But to excuse yourself is excessive. I’ve had acid reflux my entire life and I’m not apologizing to anyone for relieving pressure on my stomach. Now farting is gross in most public scenarios, but burping? No.
I know grown men that will suppress it so hard they basically choke on it, and say “excuse me” like little princesses. Even when outdoors and in a very casual setting. Women are especially conscious of it, I think it’s totally cool when a woman burps unashamedly.
LET IT OUT!!!! UNABASHED BURPERS UNITE!
