Rhiannon is the type of girl who will try steal yo best friend. Once she takes over, she will do everything with yo bestie and tries her very best to keep you away from your now ex bstfrn!
She will also pretend shes friends with popular people so people like her and are unaware of the sad and horrible truth of Rhiannon.
All though she has a good side. She is very loyal to her friends and does a lot for them but if she suddenly rejects you, just try keep yo bestie (this is from my experience)

Get a Rhiannon mug for your Aunt Sarah.

A FAKE bitch who most likely has FOMO. She is most likely flat and tries to make her butt and boobs look good in mirror pics or pictures in general. She sticks out her lips where you can probably can see the inside of her mouth. If she is not apart of something she is probably going to be mad about it. She gets obsessed with makeup and wants to literally be apart of every conversation.
"I was talking to Rhiannon today."

"Oh shit what was Rhiannon mad about"
