Trololo is the nickname internet users gave to Eduard Khil's wordless song performance of “I Am Glad, 'Cause I'm Finally Returning Back Home.” Although the recording dates to the Soviet era, it spread globally in 2010 after the video was widely shared online. Its unusual vocal style, cheerful expression and lack of language barrier helped it become a lasting viral meme. Creators still use the clip because it instantly evokes early internet humor and turns normal footage into something knowingly absurd.
