The 'Trololo Guy' meme features the late Russian baritone singer Eduard Khil performing a vocalized version of the song 'I Am Very Glad, as I'm Finally Returning Back Home' in 1976. The video went viral in 2010 due to Khil’s distinctive 'trololo' vocalizations, his joyful expressions, and the surreal aesthetic of the Soviet-era television set. It quickly became the ultimate anthem for 'trolling' on the internet, often used to mock someone's misfortune or to signal a lighthearted prank. Eduard Khil embraced his late-career international fame, and the meme remains a cornerstone of early YouTube culture, symbolizing pure, nonsensical internet joy.
