They’re talking about the meme. Walz’s comment was an “if you know, you know” kind of joke. Totally fine and funny. The meme, however, distilled it down to a “direct” quote that he didn’t even say, calling Vance a “couch fucker”–you don’t need to look that up to take issue with it.
I’m not sure I have an issue with the meme, but I see their point.
It’s from the gymnastics balance beam final. The silver medalist is Zhou Yaqin from China.
