@FireMonkey when I first saw it in April I immediately believed it was a bit odd but certainly not an overtly sexual act in any way. The way the crowd laughed didn't sound nervous though so I knew it was a kind of joke. But I'm a multicultural American. I can easily see how the Chinese propagandists fucked with the average Westerner's mind.

That's about how I felt when I saw it. I knew there had to be something innocent in it.
