A girl that you have fun with (usually in a sexual sense) that you would never be caught with in public.
--derived from a guy riding a scooter, which is perceived as something that is very fun to ride but your friendswill make fun of you when they see you!!!!
the girlfriend of a scooterer. these girls love their scooter boyfriends. They are very loyal and will sometimes even hug their scooter boyfriend in public. A scooter girlfriend is every tween's dream.
Wow Bradley! I can't believe you have a scooter girlfriend already! We're 12 and she's like 12 and a half already. I've seen you guys hug in public. How does it feel to hold hands with a girl?
