Mangs slept with an cosplayer, they were both drunk. They both woke up in a compromising position and absolutely nothing happened between them. The woke crowd took this exactly as what you'd expect.
Now Mekkah and a few others had cut ties with their most successful co-host and Mangs is just winging it on his own after a few public apologies and getting his shit together. Now he's more successful than he was, earlier. And it's making this fat autist seethe because of his "strong sense of justice" thing (seriously, he was wheezing about that old Johnny Somali video)
