A beautiful, hot girl who is perfect at everything. Anything she tries to do, she's the best at. Guys love her and girls want to be her and cant help but want to hang out with her. She comes off as crazy, outgoing, and popular, but she's really unstable on the inside. She can look really sad sometimes and plays the old "im tired." She is great to have fun with but isn't always dependable as a friend. She knows when enough is enough but at the same time she'll leave you for a more popular person if she gets the opportunity to be close with them. In the end shes there for you though. Serinas are crazy complicated people who seem like typical smart perfect gorgeous popular girls. OH BTW shes reaaaalllly smart.
"Ugh, I'm so jealous of that girl. she's such a serina"
"Did you hear serina crying in the bathroom?"
"No I thought she was so outgoing and self-confident."
