The most common Norwegian term for hooch/moonshine (spirits that
are manufactured without permission). Common synonyms are
"HB", "himkok" and "heimert".
The Norwegian word "brenne" is polysemous - it can
mean both "distill" and "burn". Therefore, after
the introduction of CD writers (CD burners) to the home market, the
term "hjemmebrent" has caught on as a joking term for CDs
that are created by such devices. They are "burned at home",
as liquour is "distilled at home".
Not only is this delightful word-play, but since most of what is written
onto CDs is in fact copyrighted data, the expression draws attention
to the similarities between illicit distilling, and unauthorized
copying of data: both are strictly speaking illegal, but in most cases
tolerated, at least as long as it's for your own use.
