Hangul's Today : Hang Up

umm... just wondering... all this time i've always ended my phone call to oppa with the word "hang up" coz i always want him to hang up first. so i wonder how to say that in korean.. and... today i watched k-drama "the world within/the world that they live in" and got the word ^^ .. i didn't check it yet and ask oppa yet but i guess i'll just put it here since it's only a single word.
끊으 = [kkunh u] which means "hang up"
ah, and other than that word, i also got some other new words : gidae, mul bba, sae ki(haha i won't tell what it means ^^;;;)
