MJ

Margaret Junior, better known as "", is the daughter of Margaret Flynn and a minor character in the Fox series The Cool Kids.

MJ first appears in "Margaret Jr.", when she arrives at Shady Meadows jobless, homeless and looking for her mother to bail her out. She seems to have a history of running to Margaret for help, and doesn't react well when Margaret forces her to grow up.

Her father's name is Kenny, and we know she has a stepmother and likely has a sister (as Margaret speaks of her daughter graduating from beauty school in Boston in "Sid's First Relationship", only one episode subsequent to MJ's appearance).

We learn in "Sid's Ex-Wife" that either she or her sister was conceived at a Fleetwood Mac concert and as a result has the middle name of "Tusk".
