1. A fall in which the climber is swung into the rock caused by a hard catch.
2. A big lead fall.
I have seen a lot more people use the second definition then the first. However it would be my guess that the correct definition is number one but over time the definition has changed to number two.
Personally, when I am referring to a whipper I am referring to a long lead fall.
