endefester

Endefester is a term used in online communities to denote either an event or a person associated with celebrating the conclusion of a project, era, or update. It is informal and often humorous, and usage varies across communities.

The word is likely a portmanteau of end and fest (short for festival or celebration), with the -er suffix forming a noun for a person or thing. The term does not have a sanctioned definition in any official lexicon, and its meaning can differ between contexts.

Usage and scope: In gaming and software fandoms, endefesters organize or participate in retrospectives, countdowns, streaming sessions, or informal meetups to mark endings such as the completion of a game, the end of a long-running patch cycle, or the closure of a project. The term can refer to either the organizer, the event, or the spirit of the celebration itself, depending on how a community uses it.

Notable usage: The term is rare and largely confined to niche online communities; references outside these circles are scarce. Because it lacks formal adoption, its interpretation remains fluid and context-dependent.
