A physical form of punishment, usually as a result of some out of line action or comment made by the recipient. An asskicking can refer to any kind of beating, but is typically used to refer to violence between two equals (physical or otherwise). Beating up your dog, for instance, is not an asskicking. It does, however, make you an asshole, and if I ever find out about it, I'm coming after you with a large gardening implement such as a hoe or a rake, biatch.
