Ryanna is probably the best girl you will ever meet! She's beyond gorgeous, sexy, smart, sweet, and all around a great girl. Normally has a great ass and a hot body. She cares about her friends and family and would do anything for them. She's very wise and has a very unique perspective on things. She can be a bitch sometimes and definitely has an attitude. If you don't know a Ryanna, your missing out.
"Damn that girl is fine. She looks like a Ryanna."
