Asian girls are extremely sensitive about the size and shape of their nose. If a white men mentions their thick, asian noses it completely crushes the asian girl.
Nonchalantly bring the shape of her nose up in conversation. Show her what you mean by placing one hand of your nose and distorting it to resemble hers.
Say the words "pig'"and "snout"; even you say them under your breath it's ok as long as she hears it. Make some "oink oink" sounds. Let her know that you know, then just walk off. Leave her with that familiar sense of crushing racial inadequacy which she fully deserves to experience.
She will feel embarrassed that she even dared talk to a white human being with normal human features and a human nose.
