A Na Na is a loud mouth, know-it-all, hateful big sister who scares you, screams when you enter her room, slaps you upside the head, makes fun of your ugly girlfriend, and makes the best food when she's pissed.
You've pranked me, slapped me, told everyone about my bald girlfriend! You're no sister, you're a real Na Na!!!

Overly frilly, feminine, girly, to the point where it becomes distasteful. Often used in the context of discussing fashion, clothing or makeup.
"That skirt looked way too na-na on Angelina, but it would look great on Hilary."
"That pink lipstick looked so na-na on her."
"That pink lipstick looked so na-na on her."
