I think I'm starting to understand it now. Yet another to each their own ;) But the fact that everyone is different - each family, each person, whether male or female - it's going to vary. With some characters I can totally see the verbal sparring reaching epic insult proportions. But with others, I see some limits. I really can't see Rodney calling John an idiot or moron unless he's really stressed or angry. Even then, I can't really see John just smiling and letting Rodney get away with it. The boys teasing and insulting each other is the norm but I do see them as having lines drawn when it comes to what they give and what they take. While with other characters, though I haven't heard them get heavily insulting, I can totally see them going that far.
