Japanese Twitter is now trending with a new kind of hashtag, basically designed to grab a ton of online attention. Called ademawashitaku naru futomomo guran puri, it translates to Thighs You'll Want to Caress. It's unclear who started the first round of pictures first, but it looks like it has caught on quite a bit.

Early examples were primarily swimsuit models as well as celebrities.

But it has since expanded to anyone who has upper legs.

Basically, whatever the tweet's sender thinks would be as per the hashtag title.

There's no rule as to how much thigh you're supposed to show.

Pictures of knee-high socks, stockings, and more, welcomed.

Short hemlines too.

Tons of examples more on Twitter.

Not the worst kind of obsession to go trending, I suppose?
