jugendwort

It's a well-known german site from the Language-books publisher "Langenscheidt" where teens can every year submit a word/words (mostly an adage) and vote at the end of the year for the most popular that were famous all the year (not because of the site).
Today it is more like voting for the "funniest" words.
Jugendwort would be called in English: Word of the youth.
