look up any word, like plopping:
the expulsion of air that sounds like a burp when you're pounding a female with your meat wand.

An ass burp is similar to a fart, in that it may be just as loud or quiet, but does not have the classic defining odor.

See also Butt Burp.
I nearly ran from the room when dad let a big one rip, but when I didn't smell anything, I realized it was just an ass burp!
