If something is "fisty" it is awesome, sweet, sick, or hardcore.
Similar to fist-worthy or Seattle's filthy.
You should use this word often to get the desired effect. When used those around should acknowledged their agreement that something is fisty, by saying it is fisty as well. One can emphasize said acknowledged agreement by firstly making a fist, then grabbing the fisted wrist or forearm. The emphasis varies on how low you are grabbing, the closer you are to the elbow the more you are acknowledging the agreement. It should be duly noted that you should never thrust the fisted arm for this is offensive, one should only use a grabbing motion while fisted arm is stationary.
