I have a brother who can puke on command. It's insane. Growing up he would do it a lot, just suddenly show you what he had been eating...then swallow it again.

Yes

Yes, just swallow air and burp it out.

I used to not be able to burp at all.  Couldnt ever burp until one night i had way too much tequila and vomitted my guts out.  From that moment on I have been able to burp.  Thx tequila.

Yes, but not always trustworthy. My wife can easily. 

Are you coming onto me?

Are there people who can't burp whenever they want?

Yes.

Yes, but it's really unpleasant for me. It's also not a full burp.
