The Bell Curve of Banter is a scale used to determine whither a joke or action is funny or "too far". One would compare the action which has just occurred with a typical bell curve with the very apex of the curve being top notch banter where everyone is having a great time. If any parties involved are adversely affected to the point where they are no longer enjoying themselves then the current exchange has surpassed the Bell Curve of Banter.
John: "Did you see that?! I just ruined Mike's chances with that girl!"
Gary:"Nah man. That's too far. You've surpassed the bell curve of banter."
Gary:"Nah man. That's too far. You've surpassed the bell curve of banter."
