The melody comes from “I Am Very Glad, as I'm Finally Returning Back Home,” composed by Arkady Ostrovsky and performed by Eduard Khil. A 1976 Soviet television recording shows Khil singing the tune with non-lexical vocal sounds rather than standard lyrics. The performance reached a new international audience when the video spread widely online in 2010. Viewers nicknamed Khil “Mr. Trololo,” and the cheerful refrain became closely associated with trolling, playful victories, ironic confidence, and surreal video edits.
