The most ghetto girl you will ever meet. A Shyianne is usually on the hipster side, hence the misspelling of the name Cheyenne because it's too "mainstream." A Shyianne is also someone who generally will not date anyone unless they are younger than her. She believes she is a cougar in the making. She's generally from a small town, a farm town but likes to delude this fact by listening to immense amounts of Lil Wayne.
Person 1: Is that Shyianne?
Person 2: Yeah, you can tell by the music she's listening to.
