Like I was watching this YouTube episode with The Boyz Sunwoo in it, and him and this lady was playing this part where he had to get her nunebr, but she keep turning him down etc.
So while they was faking out this skit, he called her "Noona", but in a flirty way.
My question is, I know Noona is to be used for older sister or in general a female that's older than you (on the male side), but why is it also used in a flirtatious, " tryna get you" way?
