Dmac's are very happy go lucky people that just love life. Dmac is the funniest person you will ever meet.
He loves kissing girls, but when he does, it means somethining. He won't just hook up with anyone, it will be someone special. Dmac is also very good looking and very flirtatious.
The best guy you will ever meet and you can't help but love him!
