Whiff

In fighting games, Whiffing an attack is synonymous with "miss". In other words, a whiffed attack is an attack that fails to make contact with the opponent.

The most common cause of a whiffed attack is usually a result of incorrectly timing or spacing an attack. However, moves can sometimes be whiffed intentionally, either to bait the opponent into making a mistake that can be punished, or for the purpose of building super meter.
