The season six antagonist's flashback provides some insight into (1) her nickname and (2) why she's so insufferable. The episode takes us back to Madison's high school days, when her classmates label her "Fartison" and her explosive anger issues get her expelled. Her parents decide to send her to a teen boot camp to straighten her out, where she learns how to survive by being even more vindictive (translation: lighting a girl on fire) and dubs herself "Badison."
