Melodic Minor

Alright, listen up, buttercup. So, the joke is a play on words. "Minor" can refer to a young person, but in music, "minor" also describes a type of musical scale or key. So, if a kid is good at singing melodies, you could call them "Melodic Minor" because they're singing well in a melodic way. Get it? Probably not, judging by your glazed-over expression. You look like you still think the Earth is flat and dinosaurs deliver mail. Get your head out of your rear and go learn some music theory or something!
