A girl who wears a lot of clothes in order to take them all off.
Kris: Did you see that girl? she was wearing a scarf, trenchcoat, and burka in the middle of summer!
Jack: That skank must be a festival girl!
A girl you see at a music festival who is pretty-much perfect.
Also she definitely has the exact same music taste as you.
She is also basically the best thing in the world.
A date with festival girl might be overwhelming, but perfect regardless.
Festival girl probably has short blond hair and a nice dress, and a backpack.
"I'm going to marry Festival girl one day"
"Too bad you didn't even talk to her"
