Danni Boy 

A Danny Boy is a boy who's the best guy in the world. He's the one you can always talk to and end up happy. Along with his gorgeous personality, he loves the head-banging hardcore rock, metal, some screamo and more. He loves to sing, but is rather shy about it. To top it off, he's around 5'10, amazing, and perfect to the girls that get to know him. But, a lucky girl has stolen his heart and is keeping it away from anyone else.

Jamie: Wow, that's a fine Danni boy
Amy: Hands off, he's mine!
