This clip comes from Adele's 2015 single Hello, the lead release from her album 25. The opening line quickly became meme material online because it is simple, instantly recognisable and easy to apply to phone-call jokes, reunion edits and overdramatic reaction videos. It spread across short-form edits, caption memes and reposted audio clips, especially when creators wanted a familiar pop reference that viewers would understand in the first second. Its staying power comes from that balance of sincerity and irony.
