It's not appropriate to do it in public places.

Cause it Makes Some People Feel Bad Cause They Have No Chance Of Ever Doing It PDAs are considered rude because no one really wants to watch a private act carried out in public. That's the reason we have doors to rooms and curtains on windows.
A burp is considered rude in public because it is seen as a bodily function that is usually done privately. Burping loudly or intentionally in public can be seen as disrespectful and offensive to those around you, as it disrupts the social norms of etiquette and can create an unpleasant or uncomfortable environment. It is generally considered polite to excuse oneself and find a private space to burp, if necessary.
