I see what you mean OP.... It's like a parent/teacher/or anyone who calls the child (person) stupid, idiot, moron, or whatever...then a child (person) begins to embrace those names.
I'm stupid.... I'm chillin with my idiots. bout to call this stupid guy.
A Terrible analogy on multiple levels.
Parents and teachers do not call themselves stupid moron idiots in an endearing manner exclusive to parents and teachers
