A synonym for burp. A burp that seems to gurgle up from your intestines, through your stomach, up the esophogas and out the mouth. The sewer burp sometimes brings liquid up with it, always sounds completely disgusting and smells worse.
Kevin: Braappp! Gurgle, gurgle.
Mark: What the hell was that?!?!?
Kevin: It's new. I perfected it this morning, and I call it the Sewer Burp.
