This is a variant of the standard Mardi Gras bead flash, in which the timid soul flashes her bra or bikini top for Mardi Gras beads.
My sister Heather was cowed by the nuns; consequently, she was only up to a Catholic girl Mardi Gras bead flash.

Maybe one of the most fantasized about types of girls ever. These young girls appear to innocent, holy, or wholesome when most are "naughty" or very sexual. Known for their really short plaid skirts. These girls mostly attract older men usually in there 30's or 40's. The most tempting jail bait there is. Its like the girl you want but can't have because you'll go to jail...for a long long time.
Middle Aged Guy: "Aw those catholic school girls, make me wish I was young again."

Freind: "Better stay away you know them girls, are pure jail bait."

In slang terms, this is the stereotype describing the woman who gives the appearance of being very conformist, wholesome, and pure of "sin" (sex, drugs, and other indulgences), but in reality has a deep compulsion to be the contrasting opposite: very promiscuous and all-around unwholesome.
At the S&M club, Harry saw several women dressed in Catholic school girl uniforms.

A catholic school girl is a girl who attends a catholic school. The girl is usually good-looking and has many secrets. At catholic schools, the girls try extra hard to look good because thats the only way to stand out with those fugly uniforms.
Boys are especially attracted to the catholic school girls because of Britney's Spears' music video a couple of years ago.

p.s. Catholic school girls are not sluttier than public school girls.

N. A normal girl like everyone else only goes to a Catholic school habitating prissy nuns and (if high school) usually no males
Wears fugly uniforms with often hemmed up skirts, black flats, and baggy sweaters. Its no suprise Britney came along and sexified them up.
Catholic school girls are usually a lot less sluttier than public school girls, don't usually wear thongs, and more than half are single. The only sexy part of them are their noticeably short skirts. *They really don't like their uniforms*
Sarah the Catholic School girl (wearing a C.S uniform): Why does everyone think we catholic school girls are sluts?

Jenn the public school girl (wearing jean shorts, a thong, and a tube top): Idk
