A short girl who everyone loves. She is bubbly, sweet, and bounces around being friends with everybody. She has a great rack and will most likely ask you for piggy back rides.
Becca: Can I have a piggy back ride?
Dude: Of course you can. You're fun sized!

A smaller-than-usual candy bar that usually comes in bags of 20 or so. Usually bought for distribution over Halloween.
I spent the whole day eating fun sized Snickers that my parents bought for Halloween.
