Burp'n Blow 

The act of burping, and then blowing the exhaust in a specific direction, as you would cigarette smoke - with the intent of keeping the fumes away from someone. Often straight up, or to the side.

I did the Ol' Burp'n Blow, so you wouldn't smell it.

Burp n blow 

The act of burping and then blowing the burp into someone else's face, so that they may enjoy your lunch/choice of alcohol/stomach acid too.

Man #1: That chili at lunch was wicked. Here taste.

(Man burps and blows in his friend's face.)

Man #2: That chili was spicy. Go Burp n blow Connie from Accounting, you can make her cry. She hates spicy food.
