I've never opened every window in the house and have never heard that term. The most windows we've ever had opened at once were 4. Two upstairs and two downstairs.
The inside of our house would be covered with yellow pollen if we opened all the windows up at once. My poor SUV has already started getting pollen on it. Allergy season is starting for us already.
I'm in Georgia and I know exactly what you mean. We don't call it burping the house; we just call it opening the front & back doors at the same time. Turn around and DHs eyes are swollen shut and he's hacking up a lung.....me neither....Never heard that term.
