A short cut way of saying "What ever"
Can be written or spoken.

Solarpunk is a movement focused on a positive, ecological vision for a future where technology is used for human-centric and ecocentric purposes. It is a literary, artistic and aesthetic sub-genre and is also closely tied to eco-political activism. Solarpunk narratives have a distinctly positive and utopian foundation in contrast to the often dystopian visions found within other "punk" science fiction genres.

A shortened term for whatever. In other words, used in an argument to admit that you are wrong without admitting it so the argument is over.
