Flo-Jo

[Rory starts walking quickly down the street, and Lorelai follows her.]
LORELAI: Oh, you’re gonna have to walk faster than that. You’re gonna have to turn into friggin’ Flo-Jo to get away from me.

Flo-Jo was the name given by the press to American track and field athlete Florence Griffith Joyner (1959-1998), who won gold and silver medals for running at the 1984 and 1988 Olympic Games. She is considered to be the fastest woman of all time.
