Fimafeng is a servant of Aegir in Norse mythology. His name means "quick service" or "handy service." In the Lokasenna, Loki kills Fimafeng during a feast for the Aesir being hosted by Aegir. This causes the Norse gods to expel Loki from the party. Loki returns to the party and offers an elaborate series of insults (flyting) of the gods.
