Sang-hee noona is so pretty. She's smart, sporty, and a beautiful voice. I wish noona would go out with me, but I found out she doesn't date any one younger than her.

Noona is when you decide to slope off for some lunchtime nookie. It is only at lunchtime between the hours of 12-2pm. It can be with someone you know or a new friend.

It is also preferable to have noona in interesting places, like on car bonnets, in parks, on your boss' desk ;) You get the idea.
