Nancy

Nancy is a one time character in the animated series South Park and appeared in the Season 8 episode, Up the Down Steroid as Jimmy Vulmer's new girlfriend. Her name might be a reference to Nancy Kerrigan an American figure skating olympian. This is possible due to the fact Nancy Kerrigan was mentioned in Damien.

Appearence
Nancy generally wears sporty clothes. She wears a black T-shirt with a yellow stripe running along the shoulder and a pair of blue trousers (most probably tracksuit bottoms) with yellow stripes as well. She also wears a blue headband and has a navel ring and wears lipstick - unusual for a 9 year old girl.

Jimmy
Nancy was Jimmy's girlfriend in 'Up the Down Steroid, they met in a free period at school, and they got on quite well even after Jimmy beat her up for Nancy threatening to break up with him. She still rooted for Jimmy at the games though.
