Ever heard about the Jargon File? It was a glossary and usage dictionary of slang used by computer programmers, made by Raphael Finkel at Stanford in 1975. It's the ancestor of The Hacker's Dictionary (1983), and The New Hacker's Dictionary (1991).

Here is its definition of a "feature":

Sometimes features are planned, but are called crocks by others.
