Sienna

A person with a mentality of a 3 year old who only gets satisfaction by snitching on someone for literally anything.

Anyone: *breathes*
Sienna: excuse teacher Ryan pimp slapped me.

this name can mean a stuck up and rude back stabbing bitch she can be fake to many people and make them believe that she is a nice person but deep down she is a fake friend. there are many siennas that can be truly nice but look closely and choose your friends smartly.

Sienna :OMG your my best friend Molly
Molly :wow thanks

Sienna says to kobi :wow i hate Molly

kobi: would choose you over my Molly any day
