muggle
[from J.K. Rowling's `Harry Potter' books, 1998] A
non-wizard. Not as disparaging as luser; implies vague
pity rather than contempt. In the universe of Rowling's enormously
(and deservedly) popular children's series, muggles and wizards
inhabit the same modern world, but each group is ignorant of the
commonplaces of the others' existence - most muggles are unaware
that wizards exist, and wizards (used to magical ways of doing
everything) are perplexed and fascinated by muggle artifacts.
In retrospect it seems completely inevitable that hackers would
adopt this metaphor, and in hacker usage it readily forms compounds
such as `muggle-friendly'. Compare luser, mundane.
