Penitenziagite

Penitenziagite ("Do Penance") is a rallying cry derived from the Latin "Poenitentiam agite," meaning the same. It has been also interpreted as a paraphrase of the Greek "πένητες διάγετε" attributed to Christ ("penites diagete"), meaning "live life as a pauper".

The phrase was used by the Dulcinian movement founded by Gerard Segarelli (1240–1300) in the 13th century, a movement named after the disciple Fra Dolcino.[1]

The phrase is used in the novel The Name of the Rose by Umberto Eco and in the Jean-Jacques Annaud movie and also a miniseries of same name. It is also used by Guillermo del Toro as Pappy McPoyle in season 8, episode 3 of It's Always Sunny in Philadelphia, "The Maureen Ponderosa Wedding Massacre".

A sample of Ron Perlman saying the word appears in the song Endemoniada, the first track on the album The Nephilim, by Fields of the Nephilim.
