A "Kai"
What a kid says when they can't spell a long name and just go with the first letter.
My kid calls his aunt Kay Kay because her name is Kathleen. It's adorable and annoying.
My cousin’s kid says 'Kay' instead of 'Kathleen.' It’s so cute, I can’t stand it.
My niece calls her teacher Kay. It’s like she’s trying to make her teacher famous.
