A term used in a humorous or ironic way by especially young people, to reflect the societal damage on their brains. The brain of a zoomer ie. a person of generation z (someone born between 1997 and 2012) has been somewhat damaged by being raised by the internet and social media, and in an economic system in decline. Gen z's have very bad prospects for the future due to ecological, social and economic crisis, which if not apparent now, lies not far in the future. Therefore the zoomer brain reflects a general societal decay. Zoomer brains are often characterized by being quite socially sensitive, anti-social, anxious, depressed, apathic and suffers from a lower attention spans the previous generations.
