hex n.
1. Short for hexadecimal,
base 16. 2. A 6-pack of anything (compare quad, sense 2). Neither usage has anything to do
with magic or black art, though the pun is appreciated
and occasionally used by hackers. True story: As a joke, some
hackers once offered some surplus ICs for sale to be worn as
protective amulets against hostile magic. The chips were, of
course, hex inverters.
