Character origin in LazyTown
Robbie Rotten is the main antagonist of LazyTown, a children’s show created by Magnús Scheving that aired from 2004 to 2014 (BBC News (UK public broadcaster)). The show’s premise: encourage exercise and nutritious eating. Robbie, in contrast, spends every episode trying to trick the town’s children into being lazy and eating junk food.
His full Icelandic name is Glanni Glæpur, which translates to “Reckless crime” (Wikipedia (community-edited encyclopedia)).
“Robbie Rotten was the perfect foil to Sportacus — lazy, clever, and endlessly theatrical. He made the show work,” show creator Magnús Scheving once explained in an interview.
The implication: Robbie Rotten’s flamboyant, scheming personality made him memorable for an entire generation of viewers.

Meme status and remixes
In late 2016, the song gained viral popularity on YouTube, spawning thousands of remixes and parodies (Wikipedia (community-edited encyclopedia)). The meme became a vehicle for fans to show support for Stefánsson after his cancer diagnosis.
