Loli-con (ロリコン) is the Japanese (or Engrish) term for "Lolita complex" (derived from the novel Lolita), the sexual attraction to underage girls. It is used to refer to anime, manga, and other visual forms of art that contain sexual/erotic representations of underage girls, and also to refer to people who are sexually attracted to underage girls (and who are not themselves underage).

"Complex" is abbreviated as "con", rather tham "com", because Japanese words can't end in an "m", but can end in a "n".

Shota-con is the underage-boy equivalent of loli-con.
