litost

Seems like a combination of jealousy, inadequacy, and inferiority complex, with a bit of revenge thrown in for good measure.

Wow. That's like the S-word, turned inside-out and fortified.

"Litost is an untranslatable Czech word. Its first syllable, which is long and stressed, sounds like the wail of an abandoned dog. As for the meaning of this word, I have looked in vain in other languages for an equivalent, though I find it difficult to imagine how anyone can understand the human soul without it."
