Someone who bitches on behalf of someone else who is unable to continue bitching for themselves.
You know it's a bitchfest when one bitch gets tired, storms out of the room, and someone else takes it upon themselves to keep bitching in their behalf, like they're some kind of relief bitcher. A regular Mariano Bitch-vera or John Papel-bitch.
