Humans are so emotionally complex we feel emotions we can't even describe very well, so all of our complex emotions tend to get lumped into generic categories such as anger or sadness.
But indescribable simply won't work for the human race, so we create words which attempt to describe or quantify these feelings, words as complex as the feels.
Unsurprisingly many of the most complicated words on the list are in German, since the German language has many longer words made up of a bunch of shorter words, such as mauerbauertraurigkeit (wall builder sadness).
Now the next time you suddenly feel one of those oddball emotions you can give it a name!
