I would like to stop run a event for a time. But if time ends it should be possible to fire the event again. 

The target of this is a mouseover effect. It shouldn't be possible to fire the event to many times. 

Sample:

1. Go over the element -> The event will be fire!
2. I leave this element and go back to the element -> The event will be not fire!
3. I enter the element later -> The event will fire again!
