ai ya
This Chinese(mainly Cantonese dialect) exclamation generally used at the end of a sentence to express frustration, trouble, and empathy. When used by non-Chinese speakers, this sounds completely ugly and dumb. Refrain from using this expression if the preceding sentence is NOT in Chinese or risk sounding like a lame wannabe.
There can be no suitable example for "ai ya" when translated in English, I will not bother.
