Burp Gun 

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.

Burp Guns are illegal in most parts of the world, and with good reason.
