1. A person who greatly enjoys reading about/watching the fictional character Hannibal Lecter, created by Thomas Harris. This enjoyment often borders on obsession. Fannibals can be found lurking in the dark recesses of the internet and are intensely devoted to the books by Harris, the movies, or the new television series.
Camille is such a Fannibal that she's created a Pinterest board dedicated to Hannibal fan art.
