Thread: scamps in a sewing circle

When cops get going investigating cops, they're worse than scamps in a sewing circle.

Actress Uma Thurman had this line in the movie Pulp Fiction : "When you little scamps get together, you're worse than a sewing circle." In this context I understood the line to mean that the scamps are men gossiping about something that happened in the movie and are being compared to women in a sewing circle who like to gossip.

I do not get the connection between scamps in a sewing circle and cops investigating cops unless it means the cops gossip about what they are doing.
