Learn the timbre of duende.

Embrace the numinous.

Frambule your own ossentulle.

Lube and a good, firm grip.

I’m going to assume you want at least one direct, serious answer.

If you really want to “speak dada”, you’ve got to embrace both absurdity as well as anti-establishment thinking. Because that’s the root of dada. The movement started as a rejection of the norms of the era, and spread into art, literature, and other forms of expression after that.

I tend to look at it as something that has lost its relevance due to having become part of western culture so effectively that the expression of dadaism is almost as bourgeois as the things it originally stood against. Hell, meme culture is a perfect example of that, in its earliest forms.

Anyway, that’s the key: absurdity and upending norms.
