The Side Special Move is a special attack introduced in Super Smash Bros. Melee. It is performed by pressing the special move button while holding "left" or "right" on the control stick. The side special move is also commonly called, forward B, side B, and smash B. Some forward B attacks are different depending on whether or not the control stick is "smashed" or simply tilted to the side. An example would be Samus' missiles, where a tilt B yields a weaker homing missile, and a smash B yields a stronger, faster missile.
