SHE's my older sister.
My older sister is a woman with a dagger!! (she's kind of a すけばん！）
someone else's older sister- or, if you're a sexist douche, you can use it about any young woman, in the sense of 'hey sweetheart, bring me more tea, chop chop!' (hence the ABU tag)
my older sister
hey sweetheart! ★★★☆☆ ABU
a disrespectful way for a guy to yell at a lady he doesn't know. Kind of like, 'Hey sweetheart, go make me some tea!'
