Girls who attend Our Lady of Mercy Academy and are involved in school activities, shaving legs on a monthly basis while hair is in asirty bun.

mercy girls make fun of class mates who wear make up to school and who fix/straighten their hair. they avoid nuns in the hallways at all costs while looking fine in plaid.
on weekends mercy girls transform into the hott hygenic girls everyone sees and are the life of the party. they go on to be fabulous women who either marry extremely wealthy men or have successful carreers. after graduation, alumni visit too often because they miss the chocolate chip mercy life.
"She's such a mercy slut"

"how dare you! she's a nice lady"

"I'm sorry, your right, i really meant Mercy Girls because it's obvious now i could never land such a hott successful girl with my ugly face"
