biliousinto

Biliousinto is a neologism used in English to describe a hypothetical tendency or state in which interpretation or mood shifts toward irritability or sourness when confronted with certain stimuli. The term is used mainly in online discussions, glossaries of invented words, and speculative fiction to label a fictional cognitive or emotional condition. It is not an established term in psychology or linguistics.

Biliousinto is a portmanteau derived from bilious, meaning relating to bile or a sour, irritable mood, and into, indicating direction or immersion. The combination conveys movement into a bilious state. The coinage is informal and typically appears with humorous or narratively descriptive intent rather than formal etymology.

In practice, biliousinto appears in word lists, fan fiction, and micro-essays to describe scenes or characters whose perception darkens as the color palette shifts to yellow-green or as a particular cadence of speech intensifies. It is commonly used as a playful shorthand rather than a scientific diagnosis.

Examples include a scene in which a character experiences biliousinto when a room fills with jaundiced light, or a blogger noting biliousinto in readers who react negatively to crude humor. The term is occasionally criticized for being opaque or whimsical, but it persists as a small-scale cultural coinage among creators.
