Formulaic language

Formulaic language (previously known as automatic speech or embolalia) is a linguistic term for verbal expressions that are fixed in form, often non-literal in meaning with attitudinal nuances, and closely related to communicative-pragmatic context. Along with idioms, expletives and proverbs, formulaic language includes pause fillers (e.g., “Like,” “Er” or “Uhm”) and conversational speech formulas (e.g., “You’ve got to be kidding,” “Excuse me?” or “Hang on a minute”).
