LORELAI: The pan, Chucky. Please.
Chucky is the villain in the 1988 horror film Child’s Play, directed by Tom Holland. In the film, a serial killer named Charles Lee Ray (Brad Dourif) is fatally shot, but transfers his soul via a voodoo spell into a doll called Chucky. After being given to a little boy, Chucky, who is animated by the spirit of Charles Lee Ray, goes on to commit murders and other violent crimes – the doll’s movements are performed by animatronics, child actors, or little people, but it is voiced by Dourif.
Child’s Play was a commercial success and got reasonable reviews; there have so far been six sequels in the franchise.
Lorelai is basically calling Rory a “little horror” (jokingly).
