frumlags

Frumlags are a narrative and game-design concept used to describe transient, memory-like sequences that interrupt a running system to reveal hidden or altered past events. They function as short, dreamlike interludes that blend actuality and recollection, often blurring lines between what the protagonist believes happened and what the world implies. Frumlags are typically triggered by specific actions or states, such as reaching a milestone, encountering a paradox, or restoring a damaged data stream. The sequences may be presented in varied styles, including distorted visuals, altered audio, or textual fragments, and they may replay events out of order or with changed details to foster ambiguity and lore.

The term is a neologism in media theory and game design, commonly understood to combine aspects of framing and sequencing with lag or delay in state presentation. It is used across interactive media to provide backstory, foreshadowing, or to explore themes of memory, identity, and subjectivity. Critics note that frumlags can enrich narrative texture when used judiciously but may disrupt pacing or cause frustration if overused or under explained. Proponents argue that, when integrated with clear player agency, they reward careful interpretation.

Related concepts include memory fragments, unreliable narration, non-linear storytelling, and flashback mechanics. There is no single canonical definition, and usage varies by developer and genre. As a design tool, frumlags are part of a broader trend toward epistemic uncertainty in interactive media.
