A generally attractive female who knows how to speak her mind but in a nice way. She has secret passions and lives for art and music. She'll do anything with or for her friends and loves talking to guys. A bit of a flirt, but any Rosellen will know how to seduce you.
Person A) Wow who's that?
Person B) That's Rosellen, of course. Who else?
