This seems to be a somewhat common pose parody and there are enough pics, add a tag for it? Pixiv has it tagged as ねこなのドーナツ (Cat doughnut)

This makes reference to Nichijou's 2nd OP, so of course it's a parody... I've been wondering if this have some tag on Danbooru though.

There's already many pics that parody both Nichijou openings, so it's not just this pose.

And yeah, tags should be created! I'd go with hyadain no kakakata kataomoi - c and hyadain no joujou yuujou for those that parody the first and second openings respectively, but that's just me looking at similar tags (don't say "lazy", listen!!, etc.). Opinions?
