Newbs andnoobs often have this problem, probably due to the thrill of firing a weapon they (hopefully) don't have in real life at high rates of fire. However, pros do it too. (Admit it!) It exclusively affects users of submachine guns (especially when dual-wielding) and full machine guns. Assault rifles are less prone to this, and semi-automatic/single-shot weapons do not experience this at all.
In general, firing machine guns in short bursts is more accurate, as barrel climb and recoil don't take effect, allowing more bullets to hit a small, moving target. It also wastes less ammo. However, stream firing has its uses, such as supressive fire against large groups of people or against large targets like vehicles.
Named after Rambo and Topper Harley from "Hot Shots: Part Deux", a mid-1990s Rambo parody. Both are infamous for firing large machine guns with seemingly unlimited ammunition.
