Huh. Okay, I'll fix it ... later (at least it's still filterable, even if slightly wrong... and people say English spelling is senseless.)

There seem to be a couple of freeform tags along those lines? But I am not finding much even there. I suspect there is more of it on Tumblr! (people may also be putting that in summaries rather than tags, especially as the tags have been less than optimally useful so far.) (I didn't actually look up the work on the E/P tag! The wrangulator shows us just the tags with minimal context. I'm saving it for a treat.)
