Infinite

An infinite is any move or technique that can be maintained indefinitely, either through skill or a bug, causing large amounts of damage while at the same time preventing the opponent to escape. Infinites disrupt the normal flow of the game, allowing players' offensive or defensive abilities to go far beyond those intended by the developers. Depending on effect and difficulty of use, certain infinites may be banned from tournament play. Infinites were not possible in Super Smash Flash due to the game's physics and how attacks worked, while some are found in Super Smash Flash 2 and may get fixed during later updates.

Trivia

 * Super Saiyan Goku's infinite only got patched when Super Saiyan Goku himself got removed.
