Beloved
archetype .
The phrase itself comes out of the
smart, self-depracating mouth of
Amy Archer, i.e.
Jennifer Jason Leigh's character in
The Hudsucker Proxy.
You know...for kids.
These girls dress and talk
smart, and hold fun girl jobs like
reporting and
secretarial work. They know what's up.
Greatly more so than the
dumb boys over whom they tend to
swoon.
