a "young lady" that attends one of the all girls high schools run by the sisters of mercy. known to be slutty, rich, and stuck-up. look great in plaid skirts. shave their legs on a monthly basis and feel the need to burp and fart in public and not care what anyone thinks about it. mercy girls are the life of the party and lovee to drink and/or smoke and/or get completely fucked up on a daily basis. they love spirit journeys and random days off.

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.
