a skullshot 

An individual extensively familiar with a variety of technical devices, yet quite unaware how to interact with the software that compliments them, especially in entertainment software, including various popular gaming titles such as WoW and BF2. This individual could even have bad teeth and have posted on forums seeking female companionship, AND have a strange but sincere fascination with boats.

VERY popular term in the Northern Virginia and Florida regions.

You just tried to use scare beast on a warrior? What a skullshot!
You spot boats more than a skullshot!
Stop teamkilling, you little skullshot!
