Gengangere

Gengangere is a play by the Norwegian playwright Henrik Ibsen. It was written in 1881 and first staged in 1882. Like many of Ibsen's better-known plays, it is a scathing commentary on 19th-century morality.
The modern Norwegian word is "Gjengangere" but the translation is reasonable, literally translated as "again walkers". Norwegians also use the term about people who frequently show up in the same places, be they pubs, parties or first nights or other places or occasions.
