Rosalynes are beautiful. They're smart, very smart. They either fall in love with a stranger VERY quickly and build a relationship, or fall in love too late with a friend that's always been there. They are very humorous, and short tempered . But patient. They hate it when people aren't who they say they are, and when people aren't real with them, so if you're not, you will most likely lose them. They're strong, so don't challenge them. And they are often underestimated but proven who they are.

A Rosalyn is a teenager in high school, and, more importantly, a babysitter.

These girls can handle almost any type of child, provided that they get paid some extra, extra, moolah on the side. Children are often intimidated or scared of her because she is just as cunning as they are.

First seen in Calvin and Hobbes.
If you ever need a babysitter for your cute, yet manipulative kids, the only one who will agree to do it is that girl across the street. She is clearly a Rosalyn.
