This cough was shared as a personal recording from someone who had become sick with a cough and fever, rather than coming from a film or show. Short illness sounds like this spread on soundboards because they are useful out of context and easy to drop into any video. The clean HD quality helped it stand out from muffled phone recordings. It remains popular for sick day jokes, school and work excuses, and reaction edits where a single cough says someone is unwell without any explanation or dialogue needed at all.
