The nicest most beautiful you will ever meet. You will love her forever and ever. The guys will love her and want to be with her all of the time. Especially guys who are older than her (1-8 years older) She's extremely pretty and all of the girls will be jealous. She's a friend to keep for your life. Stay with her, and good things will come to you. She's hot!
person 1: I love somebody

There are only two types of Siannas in this world:

NICE SIANNA- The 'nice Sianna' has different variations, but generally she is nice, straight forward, doesn't like talking bad about people and she is pretty, inside and outside.

NOT SO NICE SIANNA- The not so nice Sianna can be mean, in some cases meaner than others. The WORST 'not so nice Sianna' is always talking bad about people. She is so fake. The BEST 'not so nice Sianna' sometimes talks bad about people, but doesn't deny it, and she never does it with the intention of others hating who she's talking bad about.
Girl 1: I heard that girl is a Sianna! Is she a nice Sianna?
Girl 2: Let's hope she she is, or if not she'll ruin our lives!
