Which one should you use?

Reach for aigoo (아이고) when you're tired, frustrated, or dealing with something that just went wrong — it's a sigh more than a gasp. Use omo (어머) when something catches you off guard and you want to react to the surprise. You can also use both together: '어머, 아이고!' when something is both surprising and stressful.

FAQ

Is omo spelled 어머 in Korean?

The Hangul is 어머 (eomeo). 'Omo' is a fan romanization that caught on because it's easy to type and sounds close enough — but the actual letters are eo-meo.

Can men say omo?

Yes, though in K-dramas it's more commonly associated with female characters. In real life, anyone can use 어머 as a surprised exclamation.

What other reaction words are like these?

아이시 / 아이씨 (aish) for frustration, 헐 (heol) for disbelief, and 와 (wa) for amazement are all close relatives in the K-drama reaction vocabulary.
