Sinae's are usually blond and beautiful girls that love the beach and are one of the most amazing people to be around and be friends with. She will always laugh at your jokes and is really gunny herself but will NEVER pick a guy over her friends. All the guys love her because she is known for her good looks, charm and hot body. If you know a Sinae....keep her.
Guy: Hey Sinae, do you want to go out to the movies this weekend with me?

Sinae: Sorry I'm catching up with the girls
