layuh

LAYuh is an English-language internet slang term used as an interjection to acknowledge a claim while signaling skepticism or disbelief. It is typically written in all caps, lowercase, or with stylized punctuation (LAYuh, layuh, lay-uh) and is often used in online comments, memes, and video captions.

Origins are not precisely documented; it appears in online discourse in the late 2010s and early 2020s as part of a broader trend of expressive, sarcastic interjections. It may derive from extended vowels used to convey tone, pairing with the root "lay" as a playful inversion of "yeah" or "you."

Usage in online communication typically follows a statement considered dubious, exaggerated, or absurd. It can function as a terse rebuttal or as a preface to a joke. It is sometimes accompanied by a reaction image or caption, and might appear alongside other slang such as "sure" or "sure, layuh"—though many usages rely on sarcasm rather than literal agreement.

Impact on online discourse includes appearing in various meme formats and contributing to the tonal diversity of comment sections. LAYuh provides a compact way to register skepticism and has become one of several neologisms shaping informal digital communication.
