From Barney Bunch wiki
Rusty and Rosy and Friends, member of the Censored Bunch and a member of Waternoose Incorporated. He likes flirting with chicks, having a glass of wine, and dancing with girls. He also hates the Barney Bunch to the highest degree. He is just some typical ordinary kid who likes listening to metal and spitting on the face of Barney Bunch members. Some people say that he has a b*tt on his head but has never been proven. For some reason he actually used to be g*y and be in The Barney Bunch, but then one day he became a homophobe and now hates Beavis because he's g*y. Mike Judge himself could not explain why this happened. Some rumors say that even though he is Beavis' best friend on Beavis and Butthead, they are extreme enemies in real life. Butthead was killed by Beavis on May 19, 2015.
