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.
