E-nnui

From Encyclopedia Dramatica

E-nnui is the strange sense of listlessness and boredom that descends after realising that even the most extreme of legal pornography on the internets is just as tedious as the softcore titty shots that used to amaze you when you were eleven.

Sufferers of E-nnui often become pedophiles, furries, Christians or other degenerates, mostly because the term is French. No, seriously. Look it up.

If you have never suffered from e-nnui, ED is a bad place to be.
