1 definition by plaid demeanor

A unique and slightly spastic network of predominantly single sex schools run mostly by nuns.
Sacred heart girls are usually identified by socially unacceptable behavior in public, plaid skirts, an entire group speaking all at once, or loud squeals that cannot be understood by anyone who did not attend said school.
Contrary to popular belief, Sacred Heart Girls are not lesbians and tend to be a tad boy crazy once allowed in public.
Known for their messy hair, loud demeanors, and occasionally hairy legs.
Dude, those chicks from the Academy of the Sacred Heart know how to throw a party.
