A nickname for a Bloodborne chalice dungeon opened with the glyph 'cummmfpk,' known for a fast blood echo farming loop at its entrance.

Where did Cum Dungeon come from?

YouTuber XTrin documented the layout on August 28th, 2020, and Kotaku popularized the nickname in a January 29th, 2021 article.

What does Cum Dungeon mean?

The name comes from the first three letters of the dungeon's glyph code, 'cummmfpk,' which players type at the Hunter's Dream ritual altar.

How do you use Cum Dungeon?

Players enter the glyph 'cummmfpk,' then run the entrance loop for roughly 83,489 blood echoes per cycle, since it is a false-depth dungeon with inflated rewards.

Is Cum Dungeon still popular?

It stayed a niche gaming joke tied to r/TombProspectors and Bloodborne's chalice dungeon community after the 2021 Kotaku coverage.

Cum Dungeon is the nickname Bloodborne players gave to a chalice dungeon opened with the glyph 'cummmfpk,' holding one of the game's fastest blood echo farming loops.

Overview

The nickname comes from the first three letters of the glyph code 'cummmfpk,' which players type at Bloodborne's Hunter's Dream ritual altar to generate an identical chalice dungeon on every copy of the game1. Inside, hunters step outside the starting lamp, wait for an off-screen enemy to die in an environmental trap, teleport back to reset the encounter, and collect roughly 83,489 blood echoes per cycle1.

The space is one of the 'false-depth' chalice dungeons, player-crafted layouts that insert end-game bosses and loot into mid-game slots, so the farm pays out far more than a normal dungeon at that depth would1. Kotaku traced the specific layout to a moderator on r/TombProspectors, the subreddit that catalogs Bloodborne's 2,300-plus dungeon glyphs4.
