Clearly, someone couldn't wait for the parenting work to be done and immediately gut-flagged off-topic. (I mean come on, it has to be uploaded first before I can get a post ID to work with.)
Photos are no longer off-topic when they are used as references for multiple drawn art. And spawned off several memes. Pixiv even has a tag (tongue-out Golshi) for the specific expression on the bottom center. Further examples can also be found with a 顔芸 + ゴールドシップ search.
I felt uploading this post was important to establish the origin of the 'meme' and photo-referenced poses (that the umamusumeGold Ship is often drawn with), before the twitter post gets deleted or something.
See post #716988. That would have been completely off-topic if not for the multiple references and memes.
It's so great when you first see Gold Ship the Umamusume's crazy antics and then find out that the real horse Gold Ship was just as crazy and weird in real life lol.
Hmm... come to think of it... probably should spin this off into a general pool instead. There are probably more "Golshi makes a funny face" examples around, and there's post #4531088 which can't be childed to this because it already has a parent.
I'll work on this later. Probably name it "Golshi's Funny Faces".
