ASMR stands for autonomous sensory meridian response, a sensory phenomenon that is increasingly known to induce relaxation and counteract anxiety. ASMR is known to induce a tingling sensation which usually spreads across the scalp and back of the neck when triggered by audio and visual stimuli. ASMR videos can be categorised as food and non-food videos. The former is often paired with Mukbang which originated as a Korean trend and involves the live broadcast of a person eating, often a close-up of the ASMR artist eating or drinking. Non-food videos often place more emphasis on whispers, soft crinkles, or finger flutters that are accompanied by repeated movements that will leave sensitive viewers with goose bumps and tingles.

Autonomous sensory meridian response ASMR , sometimes auto sensory meridian response ,    is a tingling sensation that typically begins on the scalp and moves down the back of the neck and upper spine. A pleasant form of paresthesia ,  it has been compared with auditory-tactile synesthesia   and may overlap with frisson. ASMR signifies the subjective experience of "low-grade euphoria " characterized by "a combination of positive feelings and a distinct static-like tingling sensation on the skin". It is most commonly triggered by specific auditory or visual stimuli, and less commonly by intentional attention control.
