A very deep and generalised boredom with one's life.
Some high-schoolers may think they are suffering, because they're "bored and do not want to do their homework"...Yes well it's deeper than that, so no you're not suffering.
Comes from the french word ennuyeux, meaning, boring/annoying

If any of you have ever read "Education for Leisure", a poem by Carol Ann Duffy, then I can tell you the charcter most definately has this problem
