Thus the exclamation 아이구 "Aigu!" is used, with varying tonality, in keening for a dead parent, or expressing sympathy for another person's bad news, but it is also used on spilling a cup of coffee, or to express exasperation on just missing a bus, amazement on meeting a long-lost friend, or fury at losing one's job.
아이구(AIGOO) means something like "oh" or "oh no" or "oh my!" It's a Korean exclamation. could also means something similar to 'geez' Mostly used as 'geez'
아이구(AIGOO)and 아이고(AIGO)are different. In grammar, aigo is right. but people lives near Seoul used to say 아이구(aigoo). Seoul people prefer to say "우(oo)" with every end of sentence. is it funny?
