Also called a Slippery Nixie, Sloppy Näkki, or The Fiddler’
s Happy Ending. The term refers to a sex act between two or more individuals where one kneels in a swamp or bog while dressed as a Nøkken, a mythological creature from nordic folklore, while playing a fiddle as their partner(s) vigorously try to
masturbate to completion before the song is finished. If the song isn’
t finished before their partner climaxes, the semen is mixed with swamp
water or algae and rubbed onto the fiddle players face.
