Something that people at the age of 12 or under write on one's body part. It is the ritual in which to get into the PEN15 club, if u write it the correct way, the 1 looks like an I and the 5 looks like an S, so instead of looking like pen with 15 latched onto the end, it spells out PENIS.
Lynn: Wanna join a club?
Caroline: Sure! what club?
Lynn: The PEN15 club! here, this is what it is!
(Lynn writes on Caroline's arm 'PEN15'.)
Caroline: What's PEN15?... OH FUCK!! YOU JUST WROTE PENIS ON MY ARM!!
Lynn: Haha, Sara showed me!
Caroline: you mean Sara from 6th grade? you talked to someone in the grade ahead of us?
Lynn: yeah, she wrote it on my arm first...
A beautiful girl with long, dark hair. Brainiest yet most stunning girl in the grade, yet has too many friends to count! She is extremely athletic and multi-talented. Harper is the perfect girl that everyone dreams to be.
Ugh... Why can't I be more like Harper? She is like god walking the planet! so perfect! ah! i want to be her friend and learn how she does all of that stuff!
