Dash-dancing

Dash-dancing is a technique that can be performed by rapidly moving the character left and right while on the ground, causing the character to rapidly dash to the left and to the right alternately.

Competitive uses
First introduced in Super Smash Flash 2 Demo v0.9, this technique can be used by all characters. However, certain characters are able to dash-dance more effectively than others i.e. are able to dash farther when they dash-dance. Dash-dancing is used for unpredictability, making it much more difficult for the opponent to predict the player's next action. Dash-dancing can also be used to trick the opponent, such as dashing aggressively towards the opponent and then begin to dash-dance midway.
