whacker
[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.
