Trolldrycka

"Djävulskandalösaktigastronomiskalasigalopperandemoniskaönske-punschen"

is a drink prepared by the devil 'Belsebub (his symbolic familiar above) Kvackman' and the money witch 'Tyranny Vampire' (I'm not making any of this up!) in the last seven hours of New Year's Eve.

Otherwise known as "Trolldrycka" (Trolls' Drink) this epically long "perspektivord" contains seven combined words: satanic, scandalous, promiscuous, gastronomic, banquet, galloping, and demonic; which is perfectly permissible in Swedish.
