Cover art for One of the Boys lyrics by Katy Perry

I think its about a girl who has always been a tomboy and hung around her guy friends, and she has possibly had a crush on one of them for quite sometime but he has never noticed her because she was 'one of the boys' and thought of her as like a little sister but then later on over the summer she grew up and "blossomed", so all the guys started likeing her but shes over that guy cause she has other options now

its pretty relatable to most girls, as when you get older, guys who never noticed you before suddenly begin to pay attention
