pedophile - one who is into pre-pubescent children

_____phile - one who is into incest?

Is there a single word that fits into "He's a ______" to describe someone who is into incest?

A hyphenated word is fine.

  • Incestiferous, i.e. "containing incest" (dictionary.reference.com/browse/-iferous) would work with a slightly modified sentence structure. Sadly, the word is not officially recognized, so you can expect trouble should you use it. Commented Apr 9, 2015 at 12:49

  • There are plenty of vulgar phrases but they tend to relate to specific relationships (e.g. sons who have sex with their mother). There are a lot of different types of incest, from relationships between first cousins, which may or may not be considered incest depending on culture, to the Oedipal.
