Where I work, we refer to similar groups as "circle-jerks".
You should have been around Friday night when a similar thread was pulled. Of coarse some FROBL pulled the race card on Joe Hadenuf. Some of us jumped in to object, things got hot, and then the thread got pulled. The next day I found out Joe had gotten banned. I'm not sure why but I have my suspicions.
I was trying to convey that without the crude mental imagery.
Joe's been banned before and always returned. Remember his usual tag line: "I failed anger management class but they passed me anyway."
