A guy's AND girl's name.
No matter what anyone says you CAN'T turn a girl's and boy's name into a boy name. It can be both, it just depends on the parent's views on things.
Devin can totally be a girls name. I don't know why it can't. Whoever thought that its only a guy's name is wrong because it definatley can be a girl's name too.
Your only smart if you know that there's no such thing as a girl's and guy's name; it depends on the parent's views on things. DUH!!!
