IJ is short for CHIJ, or Convent of the Holy Infant Jesus, a school founded in Victoria Street by Catholic nuns and priests. There are now 13 secondary and primary schools in the family.
'IJ girls' is a generalisation for girls who study in CHIJ schools and who like to hem their school uniforms real short, wear their belts real low on their hips, and are allegedly easy when it comes to the opposite sex.
But bad rep aside, they are also known for being smart, creative and well-spoken, at least going by how alumni include actresses Andrea De Cruz and Sharon Au, singer Tanya Chua, model Charmaine Harn and Campus Superstar finalist Teresa Tseng."
The Franchise school was the only school to actually make it in.
