A phonetic spelling of the acronoym "wtf" (which means "what the fuck"). Originally created on the Darktide server message board for the MMORPG Asheron's Call.

Since its creation, wataf has taken on a variety of different meanings aside from "what the fuck".

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.
