The latest Greta-related war of words began on Wednesday, after Putin described the 16-year-old Swedish climate activist as a “kind and very sincere girl” who doesn’t understand that the “world is complex.” He added that efforts to safeguard the environment should be supported, but that using “children and teenagers” to push agendas is wrong and should be condemned.

The criticism apparently didn’t sit well with the Swedish teen, who responded with her new weapon of choice: her Twitter bio.

“A kind but poorly informed teenager,” Thunberg’s Twitter bio now reads.

Although obviously meant as an attempt to mock the Russian leader’s comments, some Twitter users argued that the new bio doesn’t accurately reflect Greta’s choleric activism.
