A Mykayla is a girl who is good at singing, and beautiful. The name often show's possession. MY Kayla, you see? (Talk about modernism...) Mykayla's are also very logical, they keep a planner for organization, and work hard at everything. To call someone a Mykayla is surely a compliment.
Person A - "You see that gorgeous girl down there in Mixed Nuts, singing louder and better than everyone else?"
Person B - "the girl with the planner next to her?"
Person A - " Yeah... She's a Mykayla, through and through"
Person B - "word"
