You know when you come out of a long K-drama marathon and you start speaking this weird mix of English and Korean? And half the time you don't even know what you're saying?
Well, here are a few sounds that we can learn:
"YAH!" means "HEY!" You can't use it to say hello, its more of an attention grabber :D
"Ah-ee-goo" is similar to "ugh" but a little bit stronger. Think of it as, "Ah-ee-goo you're so annoying" or "ah-ee-goo my back hurts."
"Eo-meo!" is like "OMG" and is usually used when you're surprised :D
"Neo" means "you" and people often yell it when they're angry and need someone (that they know really well) to pay attention. Like the boyfriend does something bad then runs away, the girl would say "YAH! Neo!" or "Hey! You!!"
"Wae" means "why" and is usually used to ask "why are you acting like this?" when being screamed in a K-drama lol ^^
Just for fun, I now leave you with Gu Jun Pyo screaming "AISHHHHH" whenever he's frustrated (it starts at 0:44)
