whacker: n. [University of Maryland: from hacker] 1. A
person, similar to a hacker, who enjoys exploring the details of
programmable systems and how to stretch their capabilities. Whereas
a hacker tends to produce great hacks, a whacker only ends up
whacking the system or program in question. Whackers are often
quite egotistical and eager to claim wizard status, regardless of
the views of their peers. 2. A person who is good at programming
quickly, though rather poorly and ineptly.
