While drinking an uncomfortable ammount of Powerthirst (or any other energy beverage with a gratuidious ammount of energy), you may experiance hump-catting, also known as shooting a large jungle cat from your lower abdomen. You must scream at an obnoxious level while doing this.

It also can be used as hump-catted, and hump-catatiousness.
When Jean chugged the can of Pepsi,he started hump-catting Mark in the face.
