I can understand flatulence being rude, as it produces an (often extremely vile) odor, plus the risk of sharting makes it a dangerous proposition in public anyhow. But unless you do it right in somebody's face, the humble burp doesn't smell like anything. It's just a normal biological noise with no side effects. Why not, I ask? Isn't objecting to burping just alimentary prudery?

Why is belching rude?
