Nolaebang seems an entirely appropriate term for karaoke.
Yeah, I don't know what Karaoke is in English beyond, well, Karaoke.
But 노래방, or Noraebang, is as I said, Singing Room (노래 - Singing, and 방 being Room).
When I went to korea before Marrying, I would often spend a couple of hours waiting while my wife was in class at one of the many: 비디오방, or (phonetically) a Pidiobang, which if you say it fast you can easily translate yourself knowing that Bang = Room.
비디오 is Pi-di-o or...Video.
Which is something that one never saw in north America. You and a bunch of your young friends want to get together and hang and watch a DVD or video, North American's would head to the local BlockBuster and rent the videos and take them home. In Korea, while they had those sort of places, they also had lots of 비디오방/Video Rooms, where, you would rent a video, they put it in a machine (DVD player/VCR) and direct you to one of the various rooms which had some chairs, couch, etc and a TV to watch it on.
Was really interesting.
