Most netizens have given Swedish climate change activist Greta Thunberg's prank to rickroll attendees of a Stockholm Climate Live concert a thumbs up as she sang and danced to Rick Astley's hit "Never Gonna Give You Up".
"Greta Thunberg just rickrolled me, and I'm here for it", one Twitter user wrote in a post, while another netizen described Thunberg's performance as the "most awesome rickroll ever".
According to one more user: "Not one person in the comments have mentioned that Greta Thunberg literally just did an irl [in real life] rickroll".
The netizen nicknamed Prof Abdul Quadir, however, dubbed the performance "the weirdest form of rickrolling", calling Thunberg the "mother of cringe".
The comments came after the Swedish newspaper Aftonbladet reported that the climate activist's appearance at the concert was her first time singing to a crowd.
The news outlet quoted Thunberg as saying that "at the end of the day, we are just teenagers fooling around with each other, not just the angry kids the media often portrays us as".
Rickrolling, which initially started on 4chan, an imageboard website, in 2007, is a form of bait-and-switch using a disguised hyperlink.
Those led to a music video believing that they are accessing some unrelated material are said to be rickrolled. In real life, rickrolling can be performed by interrupting an event with a video or audio recording of a song-meme.
