It’s a cultural thing. The way I see it, there’s absolutely no space left, while some of my African friends would see no problems if 20 people were to get on board at the next stop.
This would be a great prank/flashmob, have people dress up like this, ideally with very stiff “clothing” that doesn’t show the movement, and just sit super still.
Some day worker just blankly walks in, headphones on, completely ignorant of everything around them, goes down the aisle, takes a seat and is completely unaware of anything.
Four friends sat together when the bus was nearly empty and they got off at the previous stop just before this picture was taken. That's the most plausible explanation I can think of.
It tells us that the training data mostly consists of male statues because most pictures of greek statues are male (source: google and ddg searches). Also, when most people think of "Greek Statue", they think of something like what was generated. That is all there is to it.
Does that explain how small their dicks were, or we going to stick with the story that large ones (and those not covered by the prepuce) were considered rude and mockable?
