“Go to the ghetto on you”

[Dean sees them and waves. Lindsay glances at Rory]
LORELAI: Oh, I think she’s ready to go to the ghetto on you.

Possibly a reference to the 1998 hip-hop song, “The Geto”, by the rapper Scarface, featuring Willie D, Ice Cube, and K.B, from the album, My Homies. One part says, ” … got to go, to the ghetto”. If so, it may be an attempt to make us believe Lorelai’s earlier assertion that she is “into rap”. It sort of ends up seeming a bit racist.
