who can explain what dadaism is?

I can - In art, it's the embrace of absurdity through absurdist art.

Dadaism and eyes are surrounding all the woods in frame and in a small corner of a fat face. Banana.

It's a movement that uses absurdism and surrealism to challenge and offend traditionalism and capitalism and the assumed normalcies they espouse

It's being silly. And calling it 'art'.
