“Oppa” is the Korean term that I often use for Hugh as he is an older male. It can also be used in the context of our relationship as a pet name. Unfortunately in a crowd there are many “oppas” so Hugh often assumes it’s a woman calling out to another guy, and not to him. If I call out “Oppa” to him it doesn’t really get his attention. Calling out “Hugh” also doesn’t get his attention if we are in a loud place. Lately I’ve been calling out “oi” in a very Australian accent and have found it works so much better! Especially when I stress my Australian accent as he knows it’s immediately me. The word “oi” is used quite a bit in Australian English.
