Either a lightweight submachine gun or a large automatic pistol, commonly used by Israeli militia or African mercenaries. Named not so much from the sound they make but from the indiscriminate bullet spray they produce.

Small sub machine gun. The nickname "Burp Gun" came from the physical resemblance of the German MP38 and MP40 to a classic toy gun that fired ping pong balls. The toy was manufactured by the company "Burpco"
