Kills all tweens and/or delayedCalls/callbacks, and/or timelines, optionally forcing them to completion first. The various parameters provide a way to specify exactly which types you want to kill
//kill everything
TweenMax.killAll();
//kill only tweens, but not delayedCalls or timelines
TweenMax.killAll(false, true, false, false);
//kill only delayedCalls
TweenMax.killAll(false, false, true, false);
