Gwynie is the definition of a girl who you think is a goody-two-shoes when you first meet her, but when you get to her, you realize that on the inside she was actually a dirty dancer, spunky, insane at times, and downright sexy.
I never realized she was such a gwynie!

Wow! She's definitely a gwynie.
