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.
