pornography
erotica
porn
porno

    Still and moving images, usually of women, in
   varying states of nudity, posing or performing erotic acts
   with men, women, animals, machines, or other props.  Some say
   it degrades women, some say it corrupts young boys (who
   down-load it from the web or exchange it on
   floppy disks).  Most of it is in the form of JPEG images.
   Many websites offer porn of all sorts, almost always for a
   subscription.  It is said that these are a driving force in
   the evolution of new technology and techniques for the web.
   Advertisments for them certainly constitute a significant
   proportion of all spam.  There are even pornographic
   computer games, an early example being Mac Playmate.

   Beware - many institutions, particularly universities, have
   strict rules against their computers and networks being used
   to transfer or store such things, and you might get corrupted.
