Jayne is a very outgoing loud person. She is so gorgeous and dumb at time. Falls in love and can't stop. She has an amazing bum. Makes mistakes and makes you fall for her again.
A simple replacement for any word that you can't remember, can't be bothered to say or feel needs spicing up.
Also, it can be fun to use Jayne as a replacement for a word that rhymes with it.
